Apomictic embryos in citrus arise from:
Diploid egg
Synergids
Maternal sporophytic tissue in ovule
Antipodal cells
Apomixis is a type of asexual reproduction in which an embryo is formed without meiosis or syngamy. In citrus, the apomictic embryo arises from the maternal sporophyte tissue in the ovule. In citrus or mango, some of the nucellar cells around the embryo start dividing and protrude into the embryo sac and develop into the embryos. Thus, the correct answer is option c.
