Solution
The correct option is B lower than Gases expand on heating. So, at a higher temperature, gases occupy more volume. Since the balloon in the beaker B is inflated, the gas in the beaker occupies more volume than the one in the beaker A. Hence, the temperature of beaker B is greater than that of the beaker A.
