Answer:
<u>C. We removed the training wheels from my younger sister's bike.</u>
Explanation:
A participle is a verb form that does not act as a verb in a sentence but as an adjective, that is, a word describing or modifying nouns. There are two types of participles: the present participle, which ends in <em>-ing</em>, like <em>winning</em>, and the past participle which is formed from the past tense of a verb, and therefore they usually have the endings <em>-ed, -d, -t, -en, </em>or<em> -n</em>, such as <em>swollen </em>and<em> broken.</em>
Therefore, the sentence that uses the word “training” as a participle is “C” because in here the word is giving us information about the noun “wheels.”
