• D. Osmosis

Answer 1

The correct option is B Imbibition

Swelling of wooden frames during rains is caused by the process of imbibition. The process of adsorption of water by solid particles of a substance without forming a solution is called imbibition. The water potential gradient between the absorbent ( wooden frame) and the liquid imbibed (water) is essential for imbibition.

So, the correct answer is option B.
