II. F is the husband of K.

Options

A. if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question
B. if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
C. if the data either in statement I alone or in statement Il alone are sufficient to answer the question
D. if the data in both statements I and II together are necessary to answer the question.

Answer

D

Explanation

From statement I:
M `to` daughter of K.
N `to` brother of M.
`N^(+) - overset(K?)overset(|)M^(-)`
From statement II:
`F rarr` husband of K.
`F^(+) hArr K^(-)`
Combining (I) & (II), we get

So, K is the mother of N.
Therefore, data in both the statements I and II together are necessary to answer the given question.
