Explanation:

A present participial phrase is a phrase that consists of a present participle ( a word ending with '-ing') while functioning adjectivally to describe or modify a noun or a pronoun. In the options given in the question, option A contains the adjectival phrase 'Blushing furiously' with the word blushing, being the present participle form of 'blush', and the phrase modifying the noun 'the newcomer'.

Present participial phrases should not be confused for Gerunds, which also begins with an -ing word, but do not have adjectival functions. For example:

Playing the piano is Mary's hobby.

The gerund phrase in the sentence above is Playing the piano, and it functions as the subject of the verb 'is'.

On the other hand, if it is used like this:

Playing the piano, Mary did not say a word to the boys.

Here, 'playing the piano' is a present participial phrase that describes the noun Mary.
