A person lives in a high-rise building on the bank of a river 50 m wide. Across the river is a well it tower of height 40 m. When the person, who is at a height of 10 m, looks through a polarizer at an appropriate angle at light of the tower reflecting from the river surface, he notes that intensity of light coming from distance X from his building is the least and this corresponds to the light coming from light bulbs at height 'Y' on the tower. The values of X and Y are respectively close to (refractive index of water = `4/3`)

Options

A. 25m, 10m
B. 13m, 27m
C. 22m, 13m
D. 17m, 20m
