Asiddha hetu fails because the alleged reason does not exist or is not known to exist in the paksha. Since the foundational fact is missing, no valid inference can proceed from it. Nyaya lists several subtypes depending on why the hetu is unestablished. Thus the defective reason described in the stem is asiddha.

Option A:
Option A, viruddha, focuses on reasons that prove the opposite conclusion, not on absence of the reason in the subject.

Option B:
Option B is correct because asiddha literally means “unaccomplished” or “unproved” and captures the idea that the reason has not been successfully shown in the very locus where it is needed.

Option C:
Option C, badhita, involves reasons whose supposed vyapti is contradicted by stronger evidence, even if they are present in the paksha.

Option D:
Option D, nirvikalpa, describes a kind of indeterminate perception and is not a classification of hetu at all.
