Answer : d
Hints & Solutions
(d) The phenomenon in which female gamete develops into embryo without getting fused with male gamete (fertilisation) is called parthenogenesis. Autogamy is a form of self-fertilisation in which fission of the cell nucleus occurs without division of the cell, the two pronuclei so formed reuniting to form the synkaryon. Parthenocarpy is the production of fruit without fertilisation of an egg in the ovary. Synkaryon is a nucleus formed by the fusion of two pre-existing nuclei.
