Topic: Gerunds & Participles,

Best Answer Explained in Below-:

A gerund is a verb form that ends in "-ing" and functions as a noun in a sentence. In the given options, we are looking for the sentence that does not contain a gerund.

- **Option A**: "I see a sleeping child." Here, "sleeping" is not a gerund but an adjective. It describes the noun "child." This sentence lacks any gerund since "see" is an action verb and "sleeping" merely acts as a descriptor.

- **Option B**: "Walking in the morning is good for health." In this case, "walking" is a gerund, functioning as the subject of the sentence.

- **Option C**: "He fancies visiting the Eiffel Tower." The word "visiting" here is a gerund, acting as the object of the verb "fancies."

- **Option D**: "Please stop writing." In this sentence, "writing" is a gerund as it acts as the object of the verb "stop."

Thus, option A is correct because it contains "sleeping," which does not function as a gerund, whereas the other options do include gerunds.
