Simple interest is calculated using the formula SI = (P × R × T) ÷ 100, where P is principal, R is rate and T is time in years. Substituting the given values, we get SI = (5000 × 8 × 2) ÷ 100. First multiply: 5000 × 8 = 40000 and 40000 × 2 = 80000. Dividing 80000 by 100 yields ₹800 as the simple interest.

Option A:
Option A, ₹600, would correspond to a lower effective rate or a shorter time than specified, so it does not match the formula outcome for the given data. It reflects an arithmetic underestimation.

Option B:
Option B correctly applies the simple interest formula, step by step, and arrives at ₹800. This value is consistent with both the principal and the specified rate and time.

Option C:
Option C, ₹900, is larger than the actual interest and suggests an error in multiplication or division, possibly treating time or rate incorrectly.

Option D:
Option D, ₹1000, further exaggerates the interest and would require either a higher rate or a longer period than 2 years at 8% per annum for ₹5000.
