Solution & Step-by-step Explanation
A proposition (or statement) is a declarative sentence that is either strictly true or false, but not both.
* Option A is an imperative sentence (a command).
* Option B is an interrogative sentence (a question).
* Option C is a declarative sentence stating a fact ("7 is a prime number"), which happens to be true. Thus, it is a proposition.
* Option D is an exclamatory sentence.
Therefore, Option C is a proposition.
* Option A is an imperative sentence (a command).
* Option B is an interrogative sentence (a question).
* Option C is a declarative sentence stating a fact ("7 is a prime number"), which happens to be true. Thus, it is a proposition.
* Option D is an exclamatory sentence.
Therefore, Option C is a proposition.
