Boyle's Law describes the relationship between the pressure and volume of a gas, stating that when the temperature is held constant, the product of pressure and volume is constant for a given amount of gas. This means that if you have an initial state of pressure and volume (P1 and V1), and you change the pressure and volume to a new state (P2 and V2), the relationship can be expressed as the product of these quantities remaining equal: P1 multiplied by V1 equals P2 multiplied by V2.

This formula clearly illustrates the inverse relationship: as the volume decreases, the pressure increases, and vice versa, as long as the temperature is constant. Therefore, the equation captures the essence of how gases behave under varying pressures and volumes, making it the correct representation of Boyle's Law.

Other formulas given relate to different gas laws or principles, such as the relationship of volume and temperature, but they do not accurately depict the specific principle that Boyle's Law describes.
