A)12.0 J
B)360 J
C)3 960 J
D)132 J
E)690 J

The energy delivered to the filament can be calculated using the formula:

E = VIt

where E is the energy, V is the voltage, I is the current, and t is the time.

We are given V = 12 V, I = Q/t = 30.0 C/11.0 s = 2.73 A, and t = 11.0 s.

Substituting these values into the formula:

E = (12 V)(2.73 A)(11.0 s) = 360 J

Therefore, the total energy delivered to the filament during this process is 360 J, which corresponds to choice B.
