Answer
Answer:
A. a gerund
Brief Explanations:
A gerund is a verb - ing form that functions as a noun, and nouns can be subjects. Participles function as adjectives or in verb - tenses, adjectives modify nouns, and adverbs modify verbs, adjectives, or other adverbs, so they generally don't serve as sentence subjects.
