Identify the figure of speech in the following sentence:
She was concerned to soothe the vast number of anxious faces about her.
Synecdoche is a figure of speech in which a part is made to represent the whole or vice versa. Option B) Synecdoche is the correct answer as 'faces' refer to 'people'.
The other options are wrong as metonymy, alliteration, and apostrophe mean a representative word which stands for something else, a series of words use the same consonant and an exclamation that addresses a thing, an idea, etc.
