Solution

The correct option is B If both the assertion and reason are true but the reason is not a correct explanation of the assertion
Epiphytes live on the surface of other plants for shelter and space only, hence also called space parasites. Epiphytic roots possess a covering of dead spongy tissue known as vela men. With the help of vela men, they are able to absorb water from moist atmosphere, dew and rain.
