Answer

Choice B.

Work Step by Step

A capacitor doesn’t discharge linearly in time, but exponentially. In this case, half of the remaining charge is discharged every 2.0 seconds. After 2.0 seconds, half of the charge remains. After another 2.0 seconds, half of that remains, i.e., one-fourth of the original charge remains. After another 2.0 seconds, one-eighth of the original charge remains, and so on.
