C) from the push of the ground on the
bicycle -
D) from the pull of gravity on you and
the bicycle

Answer 1

The answer is (A)

Step-by-step explanation:

The energy is in motion, so it is kinetic energy, and it is derived from the food we digest. At the top of the hill, in the absense of motion, the kinetic energy converts to potential energy.
