Answer:
C. Inference
Step-by-step explanation:
When an unfamiliar word or phrase is not directly clarified within the text, we can infer its meaning by using the information provided by the text and our prior knowledge or reasoning skills in order to figure out the meaning of the word, that is to say, we can use "Inference" as context clues. Here's an example of a sentence in which we can use inference:
Alan used to take his team seriously: he used to organize them, plan strategies for the game, guide the training practices and motivated the team for victory. He indeed was an adroit leader.
In this paragraph, we can use the surrounding information of the word adroit and our reasoning skills or prior knowledge of what a good leader does. With prior knowledge that good leaders organize, plan guide and motivate their team, we can infer that adroit means to be really good at something, adept, or skillful and that Alan was a skillful leader.
