Q. Among the four main forms of existence of life recognized in Jainism, which one of the following is not included?
(a) Deva (gods)
(b) Yaksha (demi-gods)
(c) Manushya (humans)
(d) Tiryancha (animals and plants)

Answer : B

Explanation:

Option (a) is not correct: Deva Gati (Celestial/Gods) is one of the four recognized realms of existence. It represents heavenly beings who possess supernatural powers and enjoy immense pleasures, though they cannot achieve direct liberation from this state.
Option (b) is correct: Yaksha (demi-gods) is not included as one of the four main independent forms of existence (Gatis). In Jain cosmology, Yakshas and Yakshinis are classified as protective deity figures or attendant spirits (Shasana Devatas). They are considered a sub-category or resident entity belonging inside the broader Deva Gati (specifically under the Vyantara class of celestial beings).
Option (c) is not correct: Manushya Gati (Humans) is one of the four main realms. It is considered the most critical state of existence because Moksha (liberation) can only be attained from the human form.
Option (d) is not correct: Tiryancha Gati (Animals and Plants) is one of the four main realms. It is a broad category that encompasses all non-human, non-celestial, and non-hellish living beings, ranging from one-sensed organisms (like plants, water, and earth) to multi-sensed birds and animals.
