To determine the answer to this question, we need to understand the different types of clauses and phrases.

1. A dependent clause is a group of words that contains a subject and verb but does not express a complete thought and cannot stand alone as a sentence.
2. A prepositional phrase is a group of words that starts with a preposition and ends with a noun or pronoun. It modifies a noun or verb in the sentence.
3. An adjective phrase is a group of words that functions as an adjective to describe a noun or pronoun.
4. An independent clause is a group of words that contains a subject and verb and expresses a complete thought. It can stand alone as a sentence.

Now let's analyze the sentence: "After a heated discussion, Brenda and Max decided to compromise."

The phrase "After a heated discussion" begins with a preposition "after" and ends with a noun "discussion." It modifies the verb "decided." This makes option B - "A prepositional phrase" - the correct answer.
