a. islands in the Pacific Ocean.

Explanation:

A volcanic belt is a large region of intense volcanic activity.

We can clearly see that volcanic belts are regions where volcanic activity is maximum. Volcanic belts are characterized by eruptions of gases, ash, rock, lava etc.

Such eruptions push magma to the earth's surface at high temperature. The area around the Pacific that is prone to volcanic activities is generally referred to as the 'ring of fire'.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
