A compound sentence is:

A) At least three simple sentences connected by a comma and a conjunction or by a semicolon and no conjunction.
B) No more than two simple sentences connected by a comma and a conjunction or by a semicolon and no conjunction.
C) Two or more simple sentences connected by a comma and a conjunction or by a semicolon and no conjunction.
D) Two or more simple sentences connected by a comma and no conjunction or by a semicolon and a conjunction.

My answer is C

Correct.

Correct! A compound sentence is defined as two or more simple sentences connected by a comma and a conjunction or by a semicolon and no conjunction. So, option C is the correct answer.

To arrive at this answer, it's important to understand the components of a compound sentence. A simple sentence is a sentence that expresses a complete thought and contains a subject and a predicate. A conjunction is a word that connects words, phrases, or clauses within a sentence. Some examples of conjunctions include "and," "but," "or," "nor," and "so."

In a compound sentence, two or more simple sentences are combined using a comma and a conjunction. For example: "I went to the store, and I bought some groceries." In this sentence, "I went to the store" and "I bought some groceries" are two separate complete thoughts or simple sentences connected by the conjunction "and."

Alternatively, a compound sentence can also be formed by using a semicolon instead of a comma and conjunction. For example: "She is studying for her exam; he is going for a run." In this case, "She is studying for her exam" and "He is going for a run" are two separate complete thoughts or simple sentences connected by a semicolon.

Using this knowledge, you can identify that option C accurately describes a compound sentence. Well done!
