The correct answer is option 1: chemical energy.

A dry cell is a type of battery that uses a chemical reaction to generate electricity. Inside the dry cell, there are two electrodes (a positive and a negative terminal) immersed in an electrolyte. The electrolyte consists of a paste or gel-like substance that contains chemicals such as zinc and manganese dioxide.

When the dry cell is connected to a circuit, a chemical reaction occurs between the electrolyte and the electrodes. This chemical reaction causes a flow of electrons from the negative terminal to the positive terminal, creating an electric current.

Therefore, the production of electricity in a dry cell is a result of a chemical reaction converting chemical energy into electrical energy. It is important to note that other options given can play a role in electricity production in different contexts, but for a dry cell, it is the chemical energy that is primarily involved.
