Answer 2

(b) apogamy

Explanation:

Development of gametophyte directly from sporophyte without meiosis and without forming spores, is called apospory. When prothallus (gametophyte) gives rise to a fern plant (sporophyte) directly from somatic cell without fertilization (without forming gamete) it is called apogamy. Such type of sporophyte is haploid in nature.  Development of fruit without fertilization is called parthenocarpy. Therefore, apogamy is the correct answer.
