Two statements are given followed by two conclusions as responses. You have to consider the statements to be true even if they seem to be at variance from the commonly known facts. You have to decide which of the given conclusion(s) can definitely be drawn from the given statements. Statements: The recent trend towards enjoying songs that have raps has led to only these songs topping the charts. The song which is currently topping the charts is very different from the other songs that usually top the charts. Conclusions: The song which is currently topping the charts is about a taboo subject. II.The song which is currently topping the charts does not have a rap.

A

Only Conclusion I follows.

B

Only Conclusion II follows.

C

Both the Conclusions I and II follow.
