Solution
The correct option is B perpendicular
Answer:− BLiquid surface must be perpendicular to the resultant of adhesive, cohesive and gravitational forces acting on it because if it is not perpendicular then there is a component of these forces onto liquid in surface direction that will lead to more curvature formation so as to allign itself and balance the forces to come into equillibrium.
