Given:
- A: B is my son. D is my mother.
- B: C is my wife. D is my father.
- C: D is my mother-in-law. A is my daughter.
- D: A is my grand-daughter. B is my daughter-in-law.
To find:
Which of the following statements must be true?
Solution:
We need to analyze the given statements and determine the truthfulness of each individual's claim.
Analyzing A's statement:
- A says that B is his son. This means A is either the father or mother of B.
- A also says that D is his mother. However, this contradicts the previous statement since D cannot be A's mother if B is A's son.
- Therefore, A's statement cannot be true.
Analyzing B's statement:
- B says that C is his wife. This means B is the husband of C.
- B also says that D is his father. However, this contradicts the previous statement since D cannot be B's father if C is his wife.
- Therefore, B's statement cannot be true.
Analyzing C's statement:
- C says that D is her mother-in-law. This means C is either the daughter or son of D.
- C also says that A is her daughter. However, this contradicts the previous statement since D cannot be C's mother-in-law if A is her daughter.
- Therefore, C's statement cannot be true.
Analyzing D's statement:
- D says that A is his granddaughter. This means D is either the grandfather or grandmother of A.
- D also says that B is his daughter-in-law. This means B is married to D's child.
- If we assume D is the grandfather of A, then B must be married to A's parent, which would make B D's son or daughter-in-law. This means D's statement is consistent.
- Therefore, D's statement must be true.
Conclusion:
- A's statement is not true.
- B's statement is not true.
- C's statement is not true.
- D's statement is true.
Therefore, the statement "A's father always speaks the truth" must be true.
- A: B is my son. D is my mother.
- B: C is my wife. D is my father.
- C: D is my mother-in-law. A is my daughter.
- D: A is my grand-daughter. B is my daughter-in-law.
To find:

Solution:
We need to analyze the given statements and determine the truthfulness of each individual's claim.
Analyzing A's statement:
- A says that B is his son. This means A is either the father or mother of B.
- A also says that D is his mother. However, this contradicts the previous statement since D cannot be A's mother if B is A's son.
- Therefore, A's statement cannot be true.
Analyzing B's statement:
- B says that C is his wife. This means B is the husband of C.
- B also says that D is his father. However, this contradicts the previous statement since D cannot be B's father if C is his wife.
- Therefore, B's statement cannot be true.
Analyzing C's statement:
- C says that D is her mother-in-law. This means C is either the daughter or son of D.
- C also says that A is her daughter. However, this contradicts the previous statement since D cannot be C's mother-in-law if A is her daughter.
- Therefore, C's statement cannot be true.
Analyzing D's statement:
- D says that A is his granddaughter. This means D is either the grandfather or grandmother of A.
- D also says that B is his daughter-in-law. This means B is married to D's child.
- If we assume D is the grandfather of A, then B must be married to A's parent, which would make B D's son or daughter-in-law. This means D's statement is consistent.
- Therefore, D's statement must be true.
Conclusion:
- A's statement is not true.
- B's statement is not true.
- C's statement is not true.
- D's statement is true.
Therefore, the statement "A's father always speaks the truth" must be true.

A says, B is my son and D is my mother. There is no information on C, so C can be either A's wife or A's father.
B says, C is my wife and D is my father. Now, as there is only one couple, A must be B's daughter and so all the relationship are clear.
C says, D is my mother-in-law and A is my daughter. There is no information on B, so B can be either C's husband/wife or C's father-in-law.
D says, A is my grand - daughter and B is my daughter-in-law. There is no information about C, so C can be either D's husband/wife or D's son.
So, we consider B's statement as true as all the relationship are clear in that.
Now, B is A's father and he speaks the truth. So, option C is the correct option
