C Correct answer
Explanation

Let Naimish's investment be 4x, so Rahul's is 5x (25% more). After 3 months, Deepak joins with 9x (sum of Rahul+Naimish). For one year: Naimish = 4x×12 = 48x, Rahul = 5x×12 = 60x, Deepak = 9x×9 = 81x. Ratio = 48:60:81 = 16:20:27. Deepak's 27 parts = Rs. 8.1 lakh, so 1 part = Rs. 30000. Rahul-Naimish difference = (20-16)×30000 = Rs. 120000.
