According to early Indian philosophers, the basic elements described in Pancha Tattva are Air, Earth, Fire, Sky, and Water.

Option 1: Earth, Fire, Sky, Gas, and Water - This option includes elements such as Earth, Fire, and Water which are mentioned in Pancha Tattva. However, it includes Gas instead of Air and does not include Sky.

Option 2: Air, Earth, Fire, Sky, and Water - This option correctly includes all the five basic elements described in Pancha Tattva.

Option 3: Gas, Land, Fire, Sky, and Water - This option includes Land instead of Earth and Gas instead of Air. Although Fire, Sky, and Water are correctly mentioned, it does not align with the traditional understanding of Pancha Tattva.

Option 4: Air, Earth, Fire, Land, and Water - This option includes all five basic elements mentioned in Pancha Tattva. However, it includes Land instead of Sky.

Therefore, the correct answer is Option 2. Alert - correct answer should be Option 2 (Air, Earth, Fire, Sky, and Water).
