Options
- AA-II, B-III, C-IV, D-I
- BA-I, B-II, C-III, D-IV
- CA-III, B-I, C-IV, D-II
- DA-IV, B-III, C-I, D-II
Correct answer
D. A-IV, B-III, C-I, D-II
Step-by-step solution
- A. Leclanche cell (Dry cell): This is the most common type of primary cell. At the zinc anode, the reaction is ( Zn Zn ²⁺+2 e⁻ ). Therefore, A matches with IV. - B. Ni-Cd cell: This is a secondary cell, meaning it is rechargeable. Therefore, B matches with III. - C. Fuel cell: These cells are designed to convert the energy from the combustion of fuels (like hydrogen) directly into electrical energy. Therefore, C matches with I. - D. Mercury cell: This is a small, compact primary cell that is commonly used in devi
