Answer 1

A.
Sides and bottom must be leak-proof

Answer 2

I believe the answer is: A. Sides and bottom must be leak-proof

Contaminated sharps could penetrate human skins and transfer the contamination directly into the human body, which could be dangerous for the infected's life. In order to prevent this form happening, the sides and bottom of the container must be sealed completely.
