Answer 1

Answer: (C)

Neither 1 nor 2 follows

(i) All beautiful girls are foolish.(ii) No foolish girls are smart.
Above statement says;
1. Here all beautiful girls are to be considered as foolish. But we can't say that all girls are foolish.

So, conclusion 1 does not follow.
2. Here all beautiful girls are to be considered as foolish but persons may cover both girls and boys.

So, we can't say no beautiful persons are smart.

Hence, neither 1 not 2 follow.
