Which gas law states that pressure is inversely proportional to volume at constant temperature?

Explanation:
Pressure and volume move in opposite directions when temperature stays the same. This is Boyle's Law: for a fixed amount of gas at constant temperature, the product P times V remains constant. So if you shrink the volume, the pressure must rise, and if you expand the volume, the pressure falls. You can see this from the ideal gas relation PV = nRT: with n and T fixed, P is proportional to 1/V, which is exactly the inverse relationship described. For example, halving the volume doubles the pressure. The other statements don’t describe this specific situation: one relates volume to temperature at constant pressure, another is the general gas law, and the last is just a reference condition, not a law.
