Which choice most accurately describes the method of storing electrical energy in a battery?

Question

A battery can store energy when placed in a circuit. A chemical reaction occurs inside a battery, releasing the energy to push electrons in the circuit.
A battery can store energy when placed in a circuit. Mechanical energy is stored in the battery. This energy is released to push electrons in the circuit.
A battery can store energy when placed in a circuit. A chemical reaction occurs inside a battery, releasing the energy to push protons in the circuit.
A battery can store energy when placed in a circuit. Mechanical energy is stored in the battery. This energy is released to push protons in the circuit.

Answer 1

Answer 2

hewwo! the answer is:
A) A battery can store energy when placed in a circuit. A chemical reaction occurs inside a battery, releasing the energy to push electrons in the circuit.
R_scott gives you hints on what to look for: a battery is chemical, and charge carriers are usually electrons
hope this helps <3
