What is the SI base unit of electric current?

Explanation:
Electric current is a fundamental quantity in the SI system, so its measurement uses a base unit. The ampere is defined as the unit of current, reflecting how much charge flows past a point each second. In practical terms, 1 ampere means 1 coulomb of charge passes a point per second. This makes the ampere the standard for quantifying current. The other units shown correspond to related electrical quantities: volt is for electric potential difference, ohm for resistance, and watt for power (which relates to current through P = IV or I = V/R). Since current is measured in amperes, that is the best answer.
