Dry cell is modification of

Deniell cell
Leclanche cell
Lead-acid cell
Edison cell

The correct answer is B. Leclanche cell.

A Leclanché cell is a primary cell, a type of battery that cannot be recharged. It is a common type of dry cell battery, and is used in many devices such as flashlights, toys, and portable radios.

The Leclanché cell was invented in 1866 by Georges Leclanché, a French physicist and chemist. It is a voltaic cell, which means that it produces electricity by a chemical reaction. The cell consists of a zinc anode, a manganese dioxide cathode, and a paste of ammonium chloride and zinc chloride. The anode and cathode are separated by a porous barrier, which allows ions to flow but prevents the reactants from mixing.

When the cell is in use, the zinc anode reacts with the ammonium chloride to form zinc chloride and hydrogen gas. The manganese dioxide cathode reacts with the zinc chloride to form manganese chloride and water. The flow of electrons from the anode to the cathode produces an electric current.

The Leclanché cell is a relatively inefficient battery, and its voltage decreases as it discharges. However, it is a rugged and reliable battery, and it is relatively inexpensive to manufacture.

The other options are incorrect because they are not types of dry cells. A Daniell cell is a type of wet cell battery, a lead-acid cell is a type of secondary cell (a rechargeable battery), and an Edison cell is a type of alkaline cell.
