(A) `H_(2)O_(2)+2H^(+)+2e^(-) to 2H_(2)O`
(B) `H_(2)O_(2)-2e^(-) to O_(2)+2H^(+)`
(C ). `H_(2)O_(2)+2e^(-) to 2OH^(-)`
(D) `H_(2)O_(2)+2OH^(-)-2e^(-) to O_(2)+2H_(2)O`

Options

A. (ii) and (iv)
B. (i) and (ii)
C. (iii) and (iv)
D. (i) and (iii)

Answer

A

Explanation

`O_(2)` is evolved in reactions agent, `O_(2)` is always produced , i.e., option (d) is correct
