Answer:
option B
Explanation:
Current unit is ampere (A)
Ampere will be equivalent to = ?
we know,
Current can be define as the charge per unit time

unit of charge(Q) is coulomb which is equal to C.
unit of time(t) is equal to 's'.
now,

unit of I = C/s
ampere(A) is equivalent to C/s
The correct answer is option B
