Answer:
Voltage describes the amount of energy associated with electric charge as it moves around in a circuit. Its standard unit, the volt, is related to the standard units of electric charge (the coulomb) and energy (the joule) such that one volt is equal to one joule of energy for each coulomb of electric charge.

ANSWER
The correct option is C.
John Dalton was an English Chemist, he was the one who proposed the statements that are called Dalton's atomic theory. The theory is made up of five main points, they include the following:

2. Atoms of the same elements are identical.
3. Atoms of different elements vary in size and mass.
4. Compounds are formed when elements combined in whole ratios.
5. A chemical reaction result in rearrangement of the atoms in the reactants to form products.
