a. osmosis.

b. ions.

c. edema.

d. cations.?

They form ions when they dissolve in water

When minerals or salts dissolve in water, they form ions. The correct answer is B. These ions are known as electolytes, which are often found in such solutions as salts, acids, and bases. So, when you dissolve these things in water, they will produce these types of ions.

Osmosis is a process, so it isn't a material that can be produced. Edema refers to swelling. Cations are also incorrect, because ions, not cations are formed.
