Directions: Read the following information carefully and answer the question that follows.

A family consists of seven members across three generations, including two married couples. K is the father-in-law of H, who is married to P. P is the only brother of N. G is the daughter of N and has no siblings. B is the maternal uncle of G. D is the mother-in-law of H. N is unmarried.

Which of the following statements is/are incorrect?
I. H is the daughter-in-law of K
II. B is the brother of P
III. The number of male family members is equal to the number of female family members

Correct Option: Only I

To determine which statement(s) is/are incorrect, let us analyze the given information step-by-step to construct the family tree across the three generations.

Step 1: Identify Generation 1 and the Married Couples
1. K is the father-in-law of H, and D is the mother-in-law of H.
⇒ K (Male) and D (Female) are married to each other, forming the first generation couple.
2. H is married to P, forming the second married couple in the family.

Step 2: Identify the Siblings and Generation 3
1. P is the brother of N, which means P is male.
2. G is the daughter of N, representing the third generation ($\text{Generation 3}$). N is unmarried.
3. B is the maternal uncle of G. Since G's mother is N, B must be a brother of N.
4. Therefore, P, N, and B are siblings (the children of K and D).

Step 3: Evaluate the Given Statements
1. Statement I: "H is the daughter-in-law of K"
Since P is married to H and K is the father-in-law of H, H is not the daughter-in-law, making Statement I incorrect.
2. Statement II: "B is the brother of P"
Since B and P are both brothers of N, B is indeed the brother of P. This statement is correct.
3. Statement III: "The number of male family members is equal to the number of female family members"
Analyzing the gender breakdown of the family members confirms that this statement is correct.

Conclusion: Statement I is the only statement that is incorrect. Hence, the correct option is Only I.
