Text Solution

Verified by Experts

The correct Answer is:
B
Apogamy is the reproduction without the fusion of gametes and usually without meiosis. The term may include any form of vegetative reproduction. The production of a diploid gametophyte from the sporophyte due to the absence of meiosis is known as apospory. Parthenogenesis is the development of unfertilised egg into a complete individual without fertillisation. Production and development of seedless fruits is called parthenocarpy.
