The correct option is B Apomixis
Seed formation without fertilization in flowering plants involves the process of apomixis. Although seeds, in general, are the products of fertilization, a few flowering plants such as Asteraceae and grasses, have evolved this special mechanism. Apomixis is a form of asexual reproduction that mimics sexual reproduction. It includes abnormal sexual reproduction in which egg or other cells like synergids and antipodals develop into an embryo without fertilization and meiosis.
