The metals that are employed in the battery industries are
A. Fe
B. Mn
C. Ni
D. Cr
E. Cd

Choose the correct answer from the options given below:

(A)B, C and E only✓ Correct
(B)A, B, C, D and E
(C)A, B, C and D only
(D)B, D and E only

Answer: (A)

Solution

Manganese (as

Mn O_{2}

, the cathode material in dry cells), nickel (Ni-Cd, Ni-MH batteries) and cadmium (Ni-Cd batteries) are the metals from the list used in battery manufacture. Iron and chromium are not characteristic battery-industry metals in this context.

So the correct set is B, C and E only.
