Ben Hart · Answer 1

Option (B)

Explanation:

The volatile substances are usually referred to those substances that can be easily evaporated into the atmosphere at normal temperature. Some of the common volatile present in the molten materials such as magma are H₂O, CO₂, H, N, CH₄, and SO₂.

These volatile substances are found to be mixed with the magma, which is commonly known as the molten material. When this magma comes out to the surface, the pressure decreases, and it escapes into the atmosphere forming bubbles, and these are harmful gases that are harmful to the atmosphere.

Thus, the correct answer is option (B).
