• B. potential
• C. energy
• D. current

Answer 1

The correct option is A

quantity of charge

Explanation for correct option:

In case of option A:

Quantity of electricity means net charge flown.

Mathematically, $I=\frac{Q}{t}$

where, $I=current$

$Q=charge$

$t=time$

$Q=I\times t$

$=Ampere-hour$

Explanation for incorrect options:

In case of option B:

1. Unit of potential is $volt$.

In case of option C:

1. Unit of energy is $joule$.

In case of option D:

1. Unit of current is $Ampere$.

Hence, option a is the correct answer.
