The correct option is B Cycas and Pinus both
The occurrence of polyembryony due to fertilisation of more than one egg is called simple polyembryony. Formation of extra embryos through sporophytic budding is called adventive polyembryony. Polyembryony is quite common in Cycas, Pinus, Onion, Groundnut, Mango, Lemon, Orange.
In some of these cases, a stimulus of pollination may be required. In Citrus, a seed has 240 embryos, one normal and the rest adventive, mostly nucellar. In Allium odorum, there are 5 embryos, all developed by different methods one from zygote, one from synergid, 2 from antipodal cells and one from integument of an ovule.
