Which gas law relates pressure and volume when temperature is held constant?
Boyle’s Law describes the inverse relationship between pressure and volume of an ideal gas at constant temperature (PV = constant). As per NCERT, applying relevant law/formula with correct units and sign convention leads to Boyle’s Law. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
