Synecdoche is a form of metonymy. The correct answer is B. Synecdoche is a figure of speech where a part is treated as a whole, and vice versa. For example, England lost the match, where England is a synecdoche for the English team, not the whole country. An apostrophe is a figure of speech which is used to address somebody who is not present. Simile is a comparison using words such as like or as. Metaphor is a comparison without using the comparing words (He is a lion - meaning he is as strong and fierce as a lion, and not a real lion).
