Even though there is no underlined phrase in the sentence, we can safely assume it is "turned a blind eye" because of the answer choices.
Answer:
The underline phrase means:
C. pretended not to see.
Explanation:
"To turn a blind eye" is an expression used to mean someone chooses not see something or pretends not to see it.
Suppose you work at an office and you find out one of your co-workers is stealing office supplies. You could very well report him to your superior, but you choose not to. You simply pretend you don't know anything about it. In this case, you are turning a blind eye to your co-worker's actions.
