Light is good, but too much light on your eyes will blind you. The correlation here is clear. Even though light might help you see, a strong light might make you see nothing in the same way that a very loud sound will make you hear nothing.
Since the pairing of the words <em>light:blinding </em>is based on the negative effect of the first word, the analogy we are looking for here has the same effect. So, the correct answer is sound:deafening.
