Eng.Joseph Hello,
This is my first post here,

I think the answer is A
Because when you want to know the definition of watthour,,it is the following:

Watt Hour – The quantity of electrical energy used or produced when one watt is used for one hour.

Whereas, watt is:

Watts – A watt is a measurement of total electrical power. Volts x amps = watts.

What part of the energy on an AC circuit that is to be read with an instrument says there is any time factor here. Watt hour meters measures electrical energy for a given time of hours.
