Some fathers are females.
All fathers are males.
Some fathers are mothers.

Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only conclusion III follows.
The least possible venn diagram is:
Conclusions:
I. Some males are not females. → Does not follow (As some fathers are females and all fathers are males, so it is possible that some males are not females but not definite.)
II. Some mothers are females. → Does not follow (There is no direct relation between mothers and females.)
III. Some males are mothers. → Follow (As all fathers are males and some fathers are mothers. So, definitely some males are mothers.)
