Your answer: —  ·  Correct: C
Explanation

Electric current is defined as the rate of flow of electric charge through a conductor [1]. The relationship between current (I), charge (Q), and time (t) is expressed by the formula Q = I × t. To calculate the total charge, the time must be converted into the SI unit of seconds. In this problem, the current (I) is 1.0 A and the time (t) is 10 minutes. Converting time to seconds gives 10 × 60 = 600 seconds. Applying the formula, Q = 1.0 A × 600 s, which results in a total charge of 600 Coulombs (C) [1]. This fundamental calculation demonstrates that one Coulomb is the amount of charge transferred by a current of one Ampere in one second. Therefore, the amount of electric charge flowing through the circuit is 600 C.
