Why the arbitrary choice of alphabets not originally given in the question? This makes the question of this nature UNINTERESTING.

If we sort using shortcut method of elimination by generation gap, we will go wrong.

And in Option D, what is our relation with sisters mother in law? Is It mother in law for us?

Please do clarify between B and D.

I used shortcut method like generation gap method but I am wrong. If you are using generation gap method than option d is correct. So how can solve shortcut please give the answer.

Using generation gap any option will not satisfied because some are saying answer is D but it is wrong.

Because in option D, J is the husband of N so N is female and it is given N is the brother of M in next condition so N is male so D Option is absolutely not satisfied.
