Which option correctly names the SI unit for electric current?

Explanation:
Electric current is the rate at which electric charge passes a point in a circuit. The SI unit for that rate is the ampere (A). One ampere means one coulomb of charge moves past a point every second. So current = charge per time. The coulomb measures amount of charge, not flow rate; the volt measures potential difference; the ohm measures resistance. Therefore the unit that names electric current is the ampere.
