A two wheel drive tractor, weighing $15.84 \mathrm{kN}$ with a wheel base of $2160 \mathrm{~mm}$, has the static weight divided between the front and rear axles in the ratio of 30: 70 on a horizontal level surface. The hitch point is at a height of $700 \mathrm{~mm}$ from the ground and at a horizontal distance of $120 \mathrm{~mm}$ to the rear side from the center of the rear axle. Pull acts at an angle of $12^{\circ}$ downwards from the horizontal. The maximum pull in kN, when the front wheels would just start rising from the ground is

(A) 1.48

(B) 14.46

(C) 39.04

(D) 85.54
