D Correct answer
Explanation

Kamal's annual income is Rs. 456,000, so monthly = 456000/12 = Rs. 38,000. Using ratio 84:76:89, if 76 parts = 38000, then 1 part = 500. Anu's monthly = 84 × 500 = 42000, Radha's = 89 × 500 = 44500. Sum of annual incomes = (42000 + 44500) × 12 = 86500 × 12 = Rs. 10,38,000.
