Step 1: Understanding the five Koshas in yogic philosophy.
Yogic philosophy views the human body as comprising five sheaths (koshas) surrounding the divine self (Atman). These are: Annamaya Kosha (physical body), Pranamaya Kosha (energy body), Manomaya Kosha (mental body), Vijnanmaya Kosha (wisdom body), and Anandamaya Kosha (bliss body). The outermost sheath is the Annamaya Kosha, made of food.
Step 2: Analyzing the options.
(A) Annamaya Kosha: Correct. Annamaya Kosha is the physical body and is the outermost of the five koshas.
(B) Manomaya Kosha: Incorrect. Manomaya Kosha refers to the mental sheath and is not the outermost.
(C) Pranamaya Kosha: Incorrect. Pranamaya Kosha refers to the energy body, which is inside the Annamaya Kosha.
(D) Vijnanmaya Kosha: Incorrect. Vijnanmaya Kosha refers to the wisdom body, which is deeper than the outer sheaths.
Step 3: Conclusion.
Annamaya Kosha is the outermost sheath, making option (A) the correct answer.
Final Answer: Annamaya Kosha.
