Answer:
D
Step-by-step explanation:
What is a synonym?
A synonym is a different word with a similar meaning as the original word(s).
An example of a synonym is contentful for the word happy - they mean nearly the same thing.
In this problem, the underlined word mistake means making an error. Knowing this definition, we can look at the answer choices.
A. Correction means fixing the said error; this will not be a correct synonym.
B. Accuracy means the opposite of error; this will not be a correct synonym.
C. Perfection means that there would be no mistakes made; this will not be a correct synonym.
D. We might not know what 'Blunder' means, but we know with contexual clues A, B, and C does not work, so it is answer choice D. Blunder means a careless and simple mistake.
Therefore, the correct synonym for mistake is D. Blunder.
