Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion
Step-by-step solution
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.
