Correct Answer: Handful

Solution : The first option is the correct choice.

Handful means a small quantity that can be held in one hand. In contrast to bulk, which refers to a large mass or volume, a handful is a small amount.

The meanings of the other options are as follows:

• Heavy refers to something having a great weight or being difficult to lift.

• A staple is a basic or essential item.

• Brunt is the main impact or force of something.

Therefore, the correct answer is handful.
