Which operator compares sounds?

Answer: Option C

This question is about finding the right MySQL operator to compare how similar two sounds are. Let's break down the options:
Option A: MATCH SOUNDS This doesn't exist in MySQL.
Option B: CHECK SOUNDS This doesn't exist in MySQL either.
Option C: SOUNDS LIKE This is the correct answer! MySQL uses SOUNDS LIKE to compare the sounds of two strings.
Option D: SOUNDS SIMILAR This is not a valid operator in MySQL.
So, the answer is Option C: SOUNDS LIKE. This operator helps you find words that sound similar, even if they are spelled slightly differently.
