An aqueous electrolyte consits of the ions mentioned in the list , the ion which could be most readily discharged during electrolysis [A. F e 2 + B. C u 2 + C. P b 2 + D. H + ]

Explanation

To determine which ion could be most readily discharged during electrolysis from the given options (Fe²⁺, Cu²⁺, Pb²⁺, H⁺), we need to consider the standard reduction potentials of these ions. The ion with the highest reduction potential will be discharged first during electrolysis.

### Step-by-Step Solution:

1. **Identify the Ions and Their Reduction Potentials**:
- The ions given are:
- A. Fe²⁺
- B. Cu²⁺
