Answer:
A. full of pretension
Step-by-step explanation:
Suffixes are a type of morpheme (the smallest unit of meaning of a word) that are added at the end of a word to modify that word's meaning. The suffix “ious” are used to form adjectives and means “full of something” and “possessing” and is found in words like luxurious, and pretentious. The word “pretentious”, then, means someone or something that is full of pretension.
