Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The haploid spores on germination gives rise to alga-like filamentous branched portion called Primary Protonema. This protonema develops buds, from which leafy gametophyte arises. Sometimes this primary protonema breaks up into small fragments accidentally and these fragments give rise to leafy gametophores. So, the correct answer is "Both Assertion and Reason are correct and Reason is the correct explanation for Assertion".
