Explanation / Answer

intensity after polarization = initial intensity * cos^2(angle)

angle = angle between two polarizers

in first case angle = 90 - 22.5

intensity in case A = 47 * cos^2(90 - 22.5)

intensity in case A = 6.883 W/m^2

in second case angle = 22.5

intensity in case B = 47 * cos^2(22.5)

intensity in case B = 35.845 W/m^2

in third case angle = 45 + 22.5

intensity in case C = 47 * cos^2(45 + 22.5)

intensity in case C = 6.883 W/m^2

so,

A = C < B
