Solution

The correct option is C Apospory
If a diploid egg, formed in embryo sac developed directly from nucellus, parthenogenetically grows into embryo, then the apomixes is apospory. Apospory is the process of formation of 2n (diploid) gametophyte without meiosis and spores, from vegetative or non-reproductive pars of sporophyte. So, the correct option is D.
