B Correct answer
Explanation

Let amount from B = x, from C = 14000-x. Interest from B at 12% = 0.12x, from C at 14% = 0.14(14000-x) = 1960 - 0.14x. Total: 0.12x + 1960 - 0.14x = 1800. Solving: -0.02x = -160, x = 8000. So Rs. 8000 from B, Rs. 6000 from C. Verify: 8000×0.12 = 960, 6000×0.14 = 840, total = 1800.
