Answer is Wrong!
Answer is Right!
The correct answer is B. Coulomb.
An ampere is a unit of electric current, not electric charge. The coulomb is the SI unit of electric charge. It is named after Charles-Augustin de Coulomb, a French physicist who studied electricity and magnetism. One coulomb is equal to the charge transported by a constant current of one ampere in one second.
The esu, or electrostatic unit, is a unit of electric charge that is no longer used in the SI
