The correct answer is A. :)
Answer:
protuberances - example
avarice - antonym
inundation - definition/explanation
Explanation:
The type of context clue that helps the reader determine the meaning of the word protuberances is example. Following the word protuberance is a list of protuberances: "rocks, bushes, and ledges". These are all examples.
For avarice, the context clue used is antonym. Initially the speaker says he's going to be generous, but then he uses the signal word "instead" to show that avarice is a contrast to generous. Avarice is greed.
The word inundation is further defined or explained when the rest of the sentence explains the water flooding streets and basements.
