D Correct answer
Explanation

Let original price = 100, consumption = 100. New price = 132. Desired expenditure = 111. New consumption = 111/132 × 100 ≈ 84.09. Decrease = 100 - 84.09 ≈ 15.91%. Wait - let me recalculate: Expenditure = Price × Consumption. If only 11% increase allowed: 111 = 132 × NewCons, so NewCons = 111/132 ≈ 0.8409. Decrease = (1 - 0.8409) × 100 ≈ 15.91%. Hmm, this gives ~15.9%, not 16%. Let me verify: (111/132) = 0.8409, so decrease is 15.91%. 16% is approximate.
