Three identical light bulbs, A, B, and C, are connected in the circuit shown in Figure below. When the switch S is closed,
A. the brightness of A and B decreases, and C goes out.
B. the brightness of A and B increases, but C goes out.
C. the brightness of A and B increases, and C will be about half as bright as it was.
D. the brightness of A and B remains the same as it was, but C will be about half as bright as it was.
E. the brightness of A and B remains the same as it was, but C goes out.
