Directions for Questions: These questions are based on the data given...

Understanding the Relationships
To analyze the problem, let's summarize the family relationships based on the statements provided by A, B, C, and D.
Family Structure
- From A's statement:
- A is a parent (since B is A's son).
- D is A's mother.
- From B's statement:
- B is married to C (since C is B's wife).
- D is B's father, which means D must be A's father as well.
- From C's statement:
- C states that D is their mother-in-law, which aligns with A being C's mother.
- A is C's daughter.
- From D's statement:
- D claims A is their granddaughter, confirming that D is not A's mother but rather A's grandmother.
- D states B is their daughter-in-law, which supports B's marriage to C.
Identifying the Couple
- The only couple present is B and C, as they are husband and wife.
Truthfulness Analysis
- The statements made by A and D suggest they are related as grandmother and granddaughter, while B and C are husband and wife.
- Since A’s relationship as a granddaughter is confirmed by D, and B is A's father, it can be inferred that A's father (B) must always speak the truth regarding his immediate family.
Conclusion
- Therefore, the statement "A's father always speaks the truth" is indeed true, as all of B's statements align logically without contradiction.
Final Answer
- The correct option is 'C': A's father always speaks the truth.

Directions for Questions: These questions are based on the data given...

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 relationships 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 relationships are clear in that. Now, B is A's father and he speaks the truth. So, option 3 is the correct option
