Which statement describes how energy is transferred in a resistive circuit?

In a resistive circuit, electrical energy is transformed into heat within the resistor. As current flows, electrons collide with the atoms in the resistor, transferring some of their energy to the atoms. This extra energy makes the atoms vibrate more, which we perceive as heat. So the energy from the power source is dissipated as thermal energy in the resistor. The other ideas don’t fit because a resistor doesn’t store energy chemically, it doesn’t primarily convert energy to light, and electrical energy can indeed be converted to heat in a resistor.
