Which of the following sentences exemplifies the use of a participle?

The selected sentence effectively demonstrates the use of a participle through the phrase "walking dog." In this context, "walking" functions as a present participle, describing the dog and providing more information about it. Participles are verbal forms that can act as adjectives, and they add descriptive elements to sentences. In "the walking dog," the participle creates a vivid image, indicating that the dog is currently in the action of walking, which captures the attention of those around.

This use of participles enhances the sentence's imagery and allows for a more engaging description compared to the other choices, which lack participles and instead consist of simple verb forms or states of being.
