Answer:
The correct answers are “adjectives and adverbs”.
Step-by-step explanation:
Every prepositional phrase is a group of words consisting of a preposition, its object and any words that modify the object. The object can be a noun, pronoun, gerund or clause. For example this prepositional phrase “the chocolate inside the fridge is mine” functions as an adjective, and “without a cellphone we cannot reach her” function as adverb.
