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
The embryo or the protonema in evolved mosses grow independently on the substratum from haploid spores released from spore producing structure the capsule. The diploid zygote gives rises to a multicellular structure dependent on the gametophye for either food or minerals and water.
So, the correct answer is 'If both the assertion and reason are true but the reason is not a correct explanation of the assertion'
