Best Answer Explained in Below-:

The correct answer to complete the sentence is "B) there are," and here's why it fits best in the context.

The sentence structure requires a subject and a verb that can logically connect the two ideas expressed: the qualifications of the instructors and the existence of efforts at innovative teaching. By using "there are," we create a clear and direct assertion that highlights the presence of these efforts.

"Because their instructors are highly trained professionals," acts as a causal clause, explaining why something is true or happening. The phrase "there are many efforts at innovative teaching within community colleges" serves as the main clause, stating that such efforts exist due to the instructors' qualifications.

Option A) "there" is an incomplete phrase and does not provide a verb. Option C) "that there are" introduces unnecessary complexity and doesn't fit smoothly into the sentence. Option D) "and are" implies a conjunction that doesn’t convey the intended meaning. Therefore, "there are" not only syntactically fits but also clearly communicates the intended message of the existence of multiple innovative teaching efforts in the context provided.
