If the volume of a fixed amount of gas is halved while the temperature remains constant, the pressure will

Explanation:
At constant temperature for a fixed amount of gas, pressure varies inversely with volume (Boyle’s law). The relation P1V1 = P2V2 means if the volume halves (V2 = V1/2), the pressure must double (P2 = 2P1). So the pressure doubles. The other options don’t fit because keeping temperature constant and reducing volume increases, not leaves unchanged or reduces, the pressure; quadrupling would require the volume to drop to a quarter, not half.
