Solution
The correct option is B Bryophyta
The antheridia and archegonia in Bryophytes are surrounded by a layer of sterile cells, which protects the sex organs from mechanical damage and desiccation.
The sex organs in Thallophyta are unicellular, and when multicellular every cell forms a gamete. There is no jacket of sterile cells. The zygote is liberated from the plant and passes into the resting stage. No embryo is formed after fertilization.
Hence the correct option is B.
