Statements : All fish are tortoise. No tortoise is a crocodile.

Conclusions :
I. No crocodile is a fish.
II. No fish is a crocodile.

Answer & Solution
Correct Answer: Option E
Since both the premises are universal and one premise is negative, the conclusion must be universal negative. Also, the conclusion should not contain the middle term. So, II follows; I is the converse of II and thus it also holds.
