Which one of the following words is opposite in meaning to Opaque?

Transparent

The correct answer is Option (3) → Transparent

"Opaque" means not allowing light to pass through; not transparent or hard to understand. Its opposite is "transparent," which means allowing light to pass through clearly or easy to understand.

• Option (1) → Blur: Means something that cannot be seen or remembered clearly. This is similar to opaque, not opposite.

• Option (2) → Hazy: Means unclear, misty, or not sharp, again similar in meaning to opaque.

• Option (4) → Grimy: Means dirty or covered with grime. While it suggests filth, it does not relate directly to the clarity or transparency of an object.
