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 many females in the family?

To determine the number of females in the family, let us analyze the given relationships step-by-step:

1. "J is the wife of K. K is the son of O."
- J is a female (-) married to K, who is a male (+).
- K (+) is the son of O. Hence, O is a parent of K.

2. "N is the aunt of L and K’s sibling."
- N is K's sibling. Since N is an "aunt", N must be female (-).
- Being an aunt of L means L is the child of K (or another sibling, but let us check parentage). Since there is a rule "No single parent in the family", O must be married to someone, and K and J are a married couple. If L is the child of K and J, then N (K's sister) is indeed L's aunt.

3. "P is the granddaughter of M."
- P is a female (-) because she is a granddaughter.
- Since K and J are married, their children would be L and P (making P the granddaughter of K's parents, M and O). Let's verify this structure.

4. "Q is married to P. No single parent in the family. Q is the brother-in-law of L."
- P (-) is married to Q, which means Q is male (+).
- Since Q is married to P, Q is the brother-in-law of P's sibling, L. This fits perfectly if L and P are siblings (children of J and K).
- Since O is a parent, and there are "no single parents", O must be married to M. Thus, M and O are the grandparents of L and P.

5. Determining the genders of M and L:
- "Gender of M is same as P but different as L."
- P is female (-). Therefore, M is also female (-).
- Since O is married to M, and M is female (-), O must be male (+).
- L has a different gender than M (female). Therefore, L must be male (+).

Let's list the gender of each family member:
- M: Female (-)
- O: Male (+)
- J: Female (-)
- K: Male (+)
- N: Female (-)
- L: Male (+)
- P: Female (-)
- Q: Male (+)

Counting the females in the family:
M, J, N, and P are females. Thus, there are exactly 4 females in the family.

Therefore, the correct option is Four.
