Solution

The correct option is A Dependent Variable: Independent Variable:

Time required to charge the device.

Amount of charge left in the device prior to charging.

The more the charge left in the device, the less the time required to charge the device fully.

$∴$ The time required to charge the device is dependent on the amount of charge left in the device before charging.
