The correct answer is C. extended metaphor.
Metaphor on its own is a comparison (without using words such as like or as). However, when that comparison spreads throughout a text or a poem, it is referred to as extended metaphor.
Attitude is your tone; connotation refers to your thoughts and opinions about a particular word; figurative meaning is the use of figures of speech, such as metaphor, hyperbole, etc.
