C) \[Mn{{O}_{2}},ZnC{{l}_{2}},N{{H}_{4}}Cl\] and a filter
D) \[MnC{{l}_{2}},ZnC{{l}_{2}},N{{H}_{4}}Cl\]and a filter
Correct Answer: C
Solution :
Dry cell is a primary cell. It consists two electrodes, i.e., zinc (anode) and graphite (cathode). The space between the two electrodes in the dry cell is filled with a mixture of\[Mn{{O}_{2}},ZnC{{l}_{2}},N{{H}_{4}}Cl\]and a filter.
