(C) When a water drop is placed between two glass plates,the water wets the glass surface because the angle of contact between water and glass is acute (less than $90^{\circ}$).Due to surface tension,the liquid surface tends to minimize its area.For a liquid that wets the surface (acute angle of contact),the meniscus becomes concave towards the air.This results in the liquid spreading out and forming a concave shape between the two plates,as shown in image $52-$c10.

If a water drop is kept between two glass plates,then its shape is
