Which among the following terms are distributed in the statement 'No dogs are reptiles'?
AOnly the subject term
BOnly the predicate term
CBoth subject and predicate terms ✓ Correct
DNeither subject nor predicate term
Correct answer: (C) Both subject and predicate terms
Explanation
No dogs are reptiles is a universal negative, and in it both the subject and predicate terms are distributed.
A proposition distributes a term when it refers to the whole of that term's class.
The universal negative excludes the entire subject class from the entire predicate class.
Since no dog is any reptile, all dogs and all reptiles are spoken of completely.
Both terms are therefore taken in their full extension.
