• E. if both conclusion I and conclusion II follow.

Answer 1

Answer: (A)

if only conclusion I follows.

There are three cases possible.

All trees can be tough.

This is a possibility not always correct.

Thus, conclusion I follows.

All trains being toys is not possible, because no tree is a toy.

This is a possibility not always correct.

Thus only conclusion I is correct.

Hence, Option A is correct.
