Hint: In direct current the electric charge (current) flows only in one direction while in alternating current the electric charge (current) changes direction periodically. A battery provides a constant value of current that does not change with time.

Complete answer:
Batteries are made up of one or more cells, each of which produces an electron flow in a circuit through chemical reactions. An anode (the ‘ $ - $ ’ side), a cathode (the ' $ + $ ' side), and some form of electrolyte (a substance that chemically reacts with the anode and cathode) are the three basic components of all batteries When a battery's anode and cathode are linked to a circuit, a chemical reaction occurs.

The battery provides a constant current value that does not vary over time. This is due to the fact that a battery has two terminals, one positive and one negative, with current flowing only from the positive to the negative terminal. As the current only flows in one direction, from positive to negative, it is a characteristic of DC current. As a result, the battery is a DC current source.

Hence, option A is the correct answer.

Note: Direct current is used to charge a battery, which is subsequently converted into chemical energy. When the battery is in operation, it converts chemical energy back into direct current electricity. Direct current is required to charge batteries, and batteries can only create direct current.
