Answer:
B. The volume of the liquid should be measured before it is heated.
Explanation:
A student made serious mistake that he did not measure the volume of the liquid before heating.

The initial hypothesis of the student shows that he wants to know the change in volume, so it is inevitable to calculate the initial volume to know the difference after the completion of experiment.
