Explanation:

Given Information:
- Each cell has an emf of 2.5 V.
- There are 5 rows of 4 identical cells in series.

Calculating the Equivalent Emf:
- The total emf of the battery can be calculated by multiplying the emf of a single cell by the total number of cells in series.
- Total emf = 2.5 V * 4 * 5 = 50 V

Calculating the Equivalent Internal Resistance:
- The total internal resistance of the battery can be calculated by adding the internal resistances of each cell in series.
- For option (A): 0.2 Ω * 4 * 5 = 4 Ω
- For option (B): 5 Ω * 4 * 5 = 20 Ω
- For option (C): 0.2 Ω * 4 * 5 = 4 Ω
- For option (D): 0.8 Ω * 4 * 5 = 16 Ω

Conclusion:
- The correct option is (C) 12.5 V, 0.2 Ω as it gives the closest values of equivalent emf and internal resistance to the given conditions.
