"Tom went to the grocery store, and Jerry went to the library."
The correct answer is A. Compound sentence.
A compound sentence is one composed by two independent clauses joined by a conjunction.
- Independent clauses: It is a sentence that can stand alone (It has no need of complement to have a logical meaning), in the sentence there are two independent clauses:
1. Tom went to the grocery store -- 2. Jerry went to the library.
- Conjunction: It is a connector, in this case is one of the coordinating conjunctions (For, AND, Nor, But, Or, Yet, So) and it connects the two independent clauses.
