• C.

3 Ampere

• D.

6 Ampere

A. 0,2 Ampere
Explanation
The given question states that 60 Coulombs of electric charge flow through a wire in 5 minutes. To find the electric current, we can use the formula:

Current (I) = Charge (Q) / Time (t)

Substituting the given values, we get:

I = 60 Coulombs / 5 minutes = 12 Coulombs/minute

Since 1 Ampere is equal to 1 Coulomb/second, we need to convert minutes to seconds:

12 Coulombs/minute = 12 Coulombs/60 seconds = 0.2 Ampere

Thus, the correct answer is 0.2 Ampere.
