Answer 2

Answer:

The correct answer of this question is option a,coarse sand.

Explanation:

Bulking is a property of the sand for which the volume of the sand increases when we add water in the sand.

And the bulking of the sand is highest in the coarse sand because the rough surface of the coarse sand helps to retain the water in the sand.

That's why option a is the correct answer of the question.
