According to early Indian philosophical schools (like Samkhya) and traditional Indian medicine systems (like Ayurveda), the universe and everything in it, including the human body, are composed of five basic elements, known as Pancha Mahabhuta or Pancha Tattva. These elements are Prithvi (Earth), Apas (Water), Agni (Fire), Vayu (Air), and Akasha (Sky, Ether, or Space). The terms 'Gas' and 'Land' in options A, C, and D are not the traditional terms used for these fundamental elements in this philosophical context; 'Air' (Vayu) and 'Earth' (Prithvi) are the correct traditional terms.
