Question

substances can exist in three ______: solid, liquid, and gas.

a phases

b stages

c levels

d states

e both a and d are correct

Explanation:

In the context of matter, "phases" (option a) and "states" (option d) are both correct terms to describe the solid, liquid, and gas forms of substances. "Stages" and "levels" do not accurately describe the physical forms of matter. So option e, which states both A and D are correct, is the right choice.

Answer:

e. Both A and D are correct
