"A negative charge moves in a direction opposite to that of an electric field. What happens to the energy associated with the charge?"
The charge does not disappear, so the energy represented by, say, the electron's mass and charge never dissipates or changes with motion in an electric field. Another teacher's question that is *very* poorly worded.
"A) The electric potential energy of the charge decreases, and the kinetic energy increases."
True.
