Asiddha unestablished reason type – UGC NET Question

Asiddha hetu is a defective reason that has not been successfully shown to exist in the paksha. Because the foundational fact is missing or doubtful, no valid inference can proceed from it. Nyaya further distinguishes subtypes depending on why the reason is unestablished. The core problem is that the middle term fails at the very starting point.

Option A:
Option A, badhita, indicates a reason whose vyapti is contradicted by a stronger pramana, not one that is simply absent or unproved in the subject. The hetu might be present but epistemically defeated.

Option B:
Option B, satpratipaksha, involves a reason that is counterbalanced by an equally strong opposing reason, which is different from lacking initial establishment.

Option C:
Option C, savyabhicara, deals with irregularity across instances, where the reason is present but not constantly linked with the sadhya, rather than being missing in the paksha itself.

Option D:
Option D is correct because asiddha literally means "unaccomplished" and precisely marks the failure of the hetu to be verified where it is claimed to occur. This prevents the inferential chain from getting off the ground.
