• C. Meiosis
• D. Budding

Answer: (A)

Verified step by step guidance

1. Understand the question: The problem asks which process is responsible for the development of an adult animal body from a zygote. This involves cell division and growth.
2. Review the processes listed: Mitosis, Binary fission, Meiosis, and Budding. Each of these processes involves cell division or reproduction, but they occur in different contexts and organisms.
3. Clarify the role of mitosis: Mitosis is a type of cell division that results in two genetically identical daughter cells. It is essential for growth, development, and tissue repair in multicellular organisms, including animals.
4. Eliminate incorrect options: Binary fission is a form of asexual reproduction found in prokaryotes, not in the development of multicellular animals. Meiosis is involved in the production of gametes (sperm and egg cells) for sexual reproduction, not in the growth of the body. Budding is a form of asexual reproduction seen in some organisms like hydra, not in the development of animals from a zygote.
5. Conclude that mitosis is the correct process: Mitosis is responsible for the production of the adult body of an animal from a zygote by enabling the zygote to divide and differentiate into various cell types, forming tissues and organs.
