If a scuba tank heats up, the relevant effect according to gas laws (specifically, Gay-Lussac's law) is that the pressure exerted by the gas in the tank would increase, assuming the volume of the tank remains constant.
Thus, the correct answer is:
d. The pressure exerted by the gas in the tank would increase.
