In Jain Dharma, not every jīva attains Mokṣa.

• Nigod jīva are also jīvas, so they have soul-consciousness in a very covered form.
• But only bhavya jīvas are capable of attaining Mokṣa.
• Abhavya jīvas do not attain Mokṣa.

So the correct Jain answer is:

Nigod jīvas can attain Mokṣa only if they are bhavya and, after an extremely long journey of birth and karmic purification, reach the right faith, knowledge, and conduct. But not all jīvas universally attain Mokṣa.

In short:

• All jīvas have the nature of the soul
• Not all jīvas are destined to attain Mokṣa
• Nigod is a very low life-form, not a final limit
• Mokṣa is attained by the soul that becomes fully purified

If you want, I can also explain the difference between bhavya, abhavya, and nigod in simple Jain terms.
