The correct option is A A- 1, B- 3, C- 2, D- 4

Chilling temperature for breaking dormancy ranges between 1 to 5${}^0$C.
Dormancy is the state of seed, where no germination takes place.
Photoblastic: Seeds that are stimulated to germinate by light are called as positively photoblastic seeds; whose germination is inhibited by light are called as negatively photoblastic.
In gymnosperms, there is no vegetative or asexual reproduction, but only sexual reproduction takes place. In gymnosperms, the cones contain a leafy green sporophyte and male and female gametophytes in the cones.
