Correct Answer : A.


A protonema is a creeping, green, filamentous, thread-like chain of cells which is produced by the germination of the spores and forms the earliest stage (the haploid phase) of a bryophyte life cycle. When a moss first grows from the spore, it grows as a protonema which develops into a leafy gametophore.
