B Correct answer
Explanation

Samiksha's monthly income = 120600/12 = Rs. 10,050. The ratio 84:67:89 means if 67x = 10050, then x = 10050/67 = 150. Polly's monthly = 84×150 = 12600, annual = 12600×12 = 151200. Vipul's monthly = 89×150 = 13350, annual = 13350×12 = 160200. Sum = 151200 + 160200 = 311400. Option B matches.
