Solution

The correct option is B Both B and C
The production of gemmae is a widespread means of asexual reproduction in both liverworts and mosses. In liverworts such as Marchantia, the flattened plant body or thallus is a haploid gametophyte with gemma cups scattered about its upper surface. The gemma cups are cup-like structures containing gemmae. The gemmae are small discs of haploid tissue, and they directly give rise to new gametophytes. They are dispersed from gemma cups by rainfall. Gemmae may be formed as outgrowths from some part of the gametophyte, in which case they are called as exogenous gemmae. By contrast, endogenous gemmae are formed within gametophyte cells.
Hence the correct option is D.
