In the following question, two statements are given each followed by two conclusions I and II. You have to consider the statements to be true even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements.
Statements:
(I) All young girls are modern.
(II) No modern men are superstitious.
Conclusion:
(I) No girls are superstitious.
(II) No young men are superstitious.

(I) No girls are superstitious

From the statements, there is no relation between girls and superstitious. So we cannot say that no girls are superstitious. Hence conclusion I do not follow.

(II) No young men are superstitious

From the statement II, No modern men are superstitious. Young men may or may not be superstitious. Hence conclusion II do not follow.

$$\therefore\ $$Neither conclusion I nor conclusion II follows the given statements.

Hence, the correct answer is Option C
