The option that always requires a comma before the conjunction is "compound sentence."

The option that always requires a comma before the conjunction is "compound sentence."

A compound sentence is a sentence that consists of two or more independent clauses joined together by a coordinating conjunction (such as "and," "but," "or," etc.). In order to properly punctuate a compound sentence, a comma must be placed before the coordinating conjunction. This comma helps to indicate the separation between the two independent clauses.

For example:

- "I went to the store, and I bought some groceries."

In this sentence, the comma is placed before the coordinating conjunction "and" to indicate that the two independent clauses "I went to the store" and "I bought some groceries" are separate but related.

Remember, not all types of sentences require a comma before the conjunction. It depends on the specific grammatical structure being used. But for a compound sentence, a comma before the conjunction is necessary for correct punctuation.
