Question: 1
In each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts.

Lawyers married only fair girls.
II. Suganya is very fair.

(B) If only conclusion II follows
