Solution
The correct option is B Gymnosperms
In gymnosperm, male and female gametophytes are within sporangia on sporophyte. Pollen grain in microsporangium is carried in the air and come in contact with ovule on megasporophyll. After fertilization, zygote forms embryo and ovule forms seed. Seeds are not covered. In bryophytes and pteridophytes, zygote produces sporophyte and there is no seed formation. In thallophyte, reproduction is mainly asexual and when sexual it is isogamous, anisogamous or oogamous.
