**Step 1. Understand the Definition** A compound subject consists of two or more simple subjects (nouns or pronouns) that share the same verb and are usually joined by a coordinating conjunction (such as "and" or "or"). For example, in \[ \text{Bill and Cheryl are coming.} \] the subject is the compound subject “Bill and Cheryl.” **Step 2. Analyze Each Sentence** - **Option A:** The sentence provided is just “marched in the parade.” There is no clear subject given, so it cannot be a compound subject sentence. - **Option B:** The sentence is “The five ducks swam quickly after feed pellets.” The subject here is “The five ducks,” which is a single noun phrase—not a compound subject. - **Option C:** The sentence is “One manager, along with his employees, will be chosen for the bonus.” The main subject is “One manager.” The phrase “along with his employees” is a prepositional phrase that adds extra information; it does not create a compound subject. Only “One manager” is the subject. - **Option D:** The sentence is “Bill raced after the ball and threw it back to Cheryl.” Even though there are two verbs (“raced” and “threw”), the subject remains only “Bill.” This is an example of a compound predicate rather than a compound subject. **Step 3. Conclusion** None of the sentences contain a compound subject because in each case the sentence has only one main subject or the additional elements do not function as independent subjects. \[ \textbf{None of the above.} \]
