Solution

The correct option is A Only conclusion I follows
Since one premise is particular, the conclusion must be particular and should not contain the middle term. Thus, it follows that 'Some pens are erasers, Statement I is the converse of the second premise and so it holds. Since both the premises are affirmative, the conclusion cannot be negative. Thus, II does not follow.
