When is a capacitor fully charged?
when the voltage across its plates is 
of the voltage from ground to one of its plates
of the voltage from ground to one of its plateswhen the current through the capacitor is the same as when the capacitor is discharged
when the voltage across the plates is 0.707 of the input voltage
when the current through the capacitor is directly proportional to the area of the plates

When capacitor is fully discharged - maximum charging current flows.
When capacitor is fully charged - charging current is zero.
When capacitor is fully charged - charging current is zero.

Option B is correct because a capacitor will be fully charged if the current that it discharges has the same value as the current from the source that charged it. For example a voltage source has a value of 25V with current equals to 1 Ampere. If the source is turned off, the capacitor will discharge, if the current that the capacitor discharges has a value of 1 Ampere then we can assume that is has been fully charged since a current of 1 ampere would indicate that the value of charge stored in the capacitor is 25V.

The capacitor is charge up to 63% of its time T=RC so maximum voltage should be 0.703 of its applied voltage and it is fully charged maximum upto 63% of its applied input voltage.
