Directions (67-69): Study the following information carefully and answer the questions given below:

J is the wife of K. K is the son of O. N is the aunt of L and K’s sibling. P is the granddaughter of M. Q is married to P. No single parent in the family. Q is the brother-in-law of L. Gender of M is same as P but different as L.

How J is related to N?

Correct Answer: Sister-in-law

Let us analyze the relations step-by-step from the given information to construct the family tree:
1. "J is the wife of K": This means J is female (-) and K is male (+), and they are a married couple (J ⇔ K).
2. "K is the son of O": This means O is the parent of K.
3. "N is the aunt of L and K’s sibling": Since N is K's sibling, they belong to the same generation. N is an aunt, so N is female (-).
4. Since N and K are siblings and O is K's parent, O is also N's parent. Since there is no single parent in the family, O must be married to someone, say M.
5. "P is the granddaughter of M": This means P is female (-) and belongs to the third generation. M must be married to O (the grandparents).
6. "Q is married to P": Q is male (+), and P is female (-). They are a married couple (Q ⇔ P).
7. "Q is the brother-in-law of L": Since Q is married to P, Q becomes the brother-in-law of P's sibling. Thus, L is P's sibling.
8. Since L and P are siblings, and P is the granddaughter of M (and O), L and P must be the children of K and J (as K is the son of O, and there are no other married couples mentioned in that generation to have children).
9. Let us check: "N is the aunt of L". Since N is the sibling of K (L's father), N is indeed the aunt of L, which matches perfectly.
10. We are also given: "Gender of M is same as P but different as L". Since P is female (-), M is also female (-). Since the gender of M is different from L, L must be male (+).

Now, let us determine the relationship between J and N:
- K and N are siblings.
- J is the wife of K.
- Therefore, J is the sister-in-law of K's sibling, N.
