Two statements are given, followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
I. All wings are whites.
II. No whites are wands.
Conclusions:
I. Some wings are wands.
II. No wand is a white.

​Statements:
I. All wings are whites.
II. No whites are wands.

​Conclusions:
I. Some wings are wands (Does NOT follow, Wings are a subset of whites, and no white is a wand. So, wings cannot be wands). 
II. No wand is a white (Follows, ​if no white is a wand, then it must also be true that no wand is a white).

So, Only conclusion II follows.

Thus, the correct option is: (a)​​
