Answer:
The answer is 1 J/C. This is because one volt is defined as the energy consumption of one joule per electric charge of one coulomb1. You can also write this as 1 V = 1 J/C.
The other options are not correct because:
1 N ⋅ C is the unit of electric potential energy, which is the product of voltage and charge, not the ratio.
1 J ⋅ C is the unit of action, which is a physical quantity related to energy and time, not voltage.
1 N/C is the unit of electric field strength, which is the force per unit charge, not the energy per unit charge.
