Scuba divers wear special belts to help them stay under water. These belts do this by .
A. increasing their weight
B. decreasing their weight
C. increasing their buoyant force
D. decreasing their buoyant force

A

Explanation:

Scuba divers wear belts that add to their weight so that they can more easily dive deep beneath the water's surface. Otherwise, they have to expend energy to not float back up to the top - energy that could be used to make undersea observations.

Look at the choices to see which one matches the description above: only A makes sense.

Hope this helps!
