Which of the following is a complete sentence?

A. When I was young and ambitious and loved going for walks in the park. B. Running through the park and around the school before breakfast. C. Walking with a limp as a result of the wreck. D. I went walking.

I'll be glad to check your answer.

You are right.

The complete sentence is D. I went walking.

To identify which of the given options is a complete sentence, we need to understand what makes a complete sentence. A complete sentence, also called an independent clause, must have a subject and a predicate and make a complete thought.

Let's analyze each option:

A. "When I was young and ambitious and loved going for walks in the park." - This option is a dependent clause because it starts with the subordinating conjunction "when" and does not express a complete thought. It is not a complete sentence.

B. "Running through the park and around the school before breakfast." - This option is a sentence fragment as it does not have a clear subject or a complete predicate. It is not a complete sentence.

C. "Walking with a limp as a result of the wreck." - This option is a phrase that starts with a gerund ("walking") and does not express a complete thought. It is not a complete sentence.

D. "I went walking." - This option has a subject ("I") and a predicate ("went walking") and expresses a complete thought. Therefore, D is the correct answer as it is a complete sentence.

To summarize, option D, "I went walking," is the only complete sentence.
