Answer: Option A

The process in which seeds are formed but an embryo develops without fertilization is Apomixis.
Apomixis (asexual seed formation) is the result of a plant gaining the ability to bypass the most fundamental aspects of sexual reproduction: meiosis and fertilization. Without the need for male fertilization, the resulting seed germinates a plant that develops as a maternal clone.
