M is spouse of O and parent of R. O is father-in-law of T who has two children. N is the only son of R who has no sibling. T is mother-in-law of P . V is married to P .

Who among the following is grandmother of V?

The correct option is M.

Step-by-Step Explanation:

Let us analyze the given family relations step-by-step to determine the relationship between M and V.

1. Analyze R and N's family structure:
"N is the only son of R who has no sibling."
This means R is an only child (has no brothers or sisters). R has a son named N.

2. Analyze M, O, and R:
"M is spouse of O and parent of R. O is father-in-law of T..."
Since M is the parent of R (who has no siblings), R is the only child of M and O.
O is the father-in-law of T. Since R is the only child, T must be married to R.
Since O is the father-in-law (male), M is O's spouse, so M is female (the mother of R and mother-in-law of T).

3. Analyze T, P, and V:
"T who has two children. T is mother-in-law of P. V is married to P."
T and R have two children. Since N is the only son of R, the other child of T and R must be female.
T is the mother-in-law of P, and V is married to P. Therefore, V is one of the children of T and R (married to P).

4. Determine the relationship between M and V:
- M is the mother of R.
- R is the father of V.
- Therefore, M is the paternal grandmother of V.

Thus, M is the grandmother of V.
