The correct option is B Apogamy
The development of sporophyte/embryo from gametophytic tissue without fusion of gametes is called Apogamy. eg. fern
The development of an embryo sac directly from a cell of nucellus(2n) is called apospory. eg Ranunculus
Apomixis is an unusual sexual reproduction where there is no meiosis and syngamy. eg Hawthorns
