Boyle's Law describes the relationship between the pressure and volume of a gas when the temperature is held constant. According to this principle, as the pressure exerted on a gas increases, the volume of the gas decreases, and vice versa. This inverse relationship signifies that if one value increases, the other must decrease to maintain the same product of pressure and volume.

The correct statement illustrates this concept accurately by stating that the volume of a gas is inversely related to its pressure at a constant temperature. This relationship can also be expressed mathematically as P1V1 = P2V2, where P represents pressure and V represents volume.

By recognizing this principle, we can effectively describe the behavior of gases under changes in pressure, which is fundamental to understanding gas laws and their applications in various scientific contexts.
