For each application listed in List-I, match it with the appropriate battery or cell type from List-II based on their characteristics:

(A) Transistors: Generally use a dry cell or Leclanché cell, where the anode is zinc (Zn) and the cathode is a carbon rod surrounded by manganese dioxide (MnO₂).

Therefore, (A) Transistors match with (III) Anode - Zn; Cathode - Carbon.

(B) Hearing aids: Operate using a mercury cell. The anode in this cell is a zinc-mercury amalgam, and the cathode is composed of mercury oxide (HgO) with carbon.

Thus, (B) Hearing aids match with (I) Anode - Zn/Hg; Cathode - HgO + C.

(C) Inverters: Use a lead-acid storage cell. In this type of cell, the anode consists of lead (Pb), and the cathode is a lead dioxide (PbO₂) grid.

As a result, (C) Inverters match with (IV) Anode - Pb; Cathode - Pb | PbO₂.

(D) Apollo space ship: Utilizes a hydrogen-oxygen fuel cell. The hydrogen is oxidized at the anode, while oxygen is reduced at the cathode.

Therefore, (D) Apollo space ship matches with (II) Hydrogen fuel cell.

Summary of matches:

A - III

B - I

C - IV

D - II

This corresponds with Answer Option A.
