Answer Key : (d) -

(d)

The height  to which water rises in a capillary tube is given by

where  is angle of contact ,  the radius,  the density and  acceleration due to gravity.

When lift moves down with constant acceleration, height is less than , because effective value of acceleration due to gravity increases hence  decreases.
