Study the following information carefully and answer the questions given below:

In a family of eight members, P is mother of V who is the spouse of N. M is the sister of N’s father-in-law. L is mother of M. F is only son of L and R. C is sister in-law of N and vice versa.

Four of the following five are similar in a certain pattern and related to a group, who among the following is dissimilar to others?

The correct answer is V.

Let us analyze the given family relations step-by-step to determine the gender and relationship of each family member:
1. "P is mother of V who is the spouse of N."
This means P is female (mother). V and N are married to each other (spouses).
2. "M is the sister of N’s father-in-law."
Since V is married to N, V's parent (P is the mother, so V's father is married to P) is N's parent-in-law. Specifically, V's father is N's father-in-law, which means V is the child of P and N's father-in-law. M is the sister of V's father, so M is female.
3. "L is mother of M."
L is female.
4. "F is only son of L and R."
L (mother) and R (father) have only one son, F. Since M is L's daughter, F is the brother of M and thus the father of V (N's father-in-law).
5. "C is sister-in-law of N and vice versa."
C is the sister-in-law of N, which means C is female (sister of V).

Now let us determine the gender of each person listed in the options:
- L is the mother of M, so L is female.
- M is the sister of F, so M is female.
- C is the sister-in-law of N, so C is female.
- V: F is the only son of L and R. Since F is V's father and F is the only son in that generation, V is the son of F and P. Therefore, V is male.

Among the given choices, L, M, and C are all female, while V is male. Hence, V is the one who is dissimilar from the others in the group.
