Correct option is D
∙ An Ampere is the unit of electric current in the International System of Units (SI).∙ It is defined as the flow of one Coulomb of charge per second.∙ Mathematically:1 Ampere (A)=1 Coulomb per second (C/s)This definition is based on the relationship between current (I), charge (Q), and time (t):I=tQwhere I is the current in Amperes, Q is the charge in Coulombs, and t is the time in seconds.Thus, the Ampere is equivalent to Coulomb per second.
