Use the work shown which expression is equivalent to

A). Participle phrase.

Step-by-step explanation:

'Participle phrases' are defined as the phrases that consist of a participle(present or past) followed by modifiers and their object plus any/or complements. These phrases primarily function as adjectives by providing information about a noun or pronoun in the sentence.

In the given sentence, the underlined portion('stepping from the embrace') is a participle phrase as it begins with a participle('present as it ends with 'ing') followed by the modifier prepositional phrase 'from the embrace'(as an adverb). It is functioning as an adjective as it modifies the pronoun 'she' in the sentence. Thus, option A is the correct answer.
