Explanation:
To determine if A is the mother-in-law of C, we need to find a statement in the given options that indicates the relationship between A and C as mother-in-law and daughter-in-law respectively.
Let's analyze each option:
a) D A x M C
This statement indicates that A is the mother of M, and M is the mother of C. Therefore, A is the grandmother of C. There is no indication of a mother-in-law relationship, so this option is not correct.
b) A x M x C
This statement indicates that A is the mother of M, and M is the mother of C. Again, there is no indication of a mother-in-law relationship, so this option is also not correct.
c) M C A
This statement indicates that M is the daughter of C and A. There is no indication of a mother-in-law relationship, so this option is not correct.
d) C M D x A
This statement indicates that C is the daughter of M, D is the husband of M, and A is the mother of D. Here, we have A as the mother of D, and D as the husband of C. Therefore, A is the mother-in-law of C. This option satisfies the condition, so the correct answer is option 'A'.
Conclusion:
The statement "D A x M C" indicates that A is the mother-in-law of C.
