The following sentence contains running up the stairs, he glanced apprehensively behind him. a gerund phrase as the subject a participial phrase modifying he a dangling participial phrase

The correct answer is B. a participial phrase modifying he.

The participial phrase is running up the stars - given that this is a participle, option A is incorrect. The subject of the sentence is the pronoun he, not the participle. Option C is also incorrect - given that the phrase is used correctly (it modifies the pronoun), it is not dangling. A dangling modifier is used in a wrong way because it doesn't refer to anything in a sentence - since that is not the case here, C is incorrect.

That leaves us with option B - the participial phrase is describing what the pronoun he is doing, therefore, it is modifying it.

voracity is the noun corresponding to the adjective voracious, which means (1) eager to consume a great amount of food, or (2) marked by an insatiable appetite. veracity is far more common than the rare voracity, so the latter is sometimes used in place of the former.
