D1, 2 and 3

Explanation

Parthenogenesis is embryo development from an unfertilized egg; apogamy is sporophyte development from gametophytic tissue without fertilization; and sporophytic budding (adventive embryony) is embryo formation from diploid sporophytic cells such as the nucellus or integument, again without fertilization. All three are irregular modes in which an embryo arises without the fusion of gametes, so statements 1, 2 and 3 are all correct.
