Match the entries from Column I and Column II and choose the correct order.

Options

  1. A( array lll A & B & C 3 & 2 & 1 array )
  2. B( array lll A & B & C 1 & 2 & 3 array )
  3. C( array lll A & B & C 3 & 1 & 2 array )
  4. D( array lll A & B & C 2 & 1 & 3 array )

Correct answer

C. ( array lll A & B & C 3 & 1 & 2 array )

Step-by-step solution

The correct matching between Column I and Column II is (A) Leclanche cell-anode reaction : ( Zn Zn ²⁺+2 e⁻ ) Cathode : ( MnO ₂+ NH ₄⁺+e⁻ MnO ( OH )+ NH ₃ ) (B) Fuel cell : (2 H ₂+ O ₂ H ₂ O + ) Energy (gets converted into electrical energy). (C) Ni-Cd cell : Rechargeable (secondary) cell. Hence, option (c) is correct.
