The given figure represents an experiment:

(a) Leaf A was coated with grease on both the surfaces.
(b) Leaf B was coated with grease on the lower surface.
(c) Leaf C was coated with grease on the upper surface.
(d) Leaf D was left without any application of grease.

All the four leaves A, B, C and D were left in a room for about 24 hours.

(i) Which leaf dries first? Give reason.
(ii) Which leaf dries last? Give reason.
