​According to classical Indian logicians (Naiyāyikas), which of the following arguments commits the fallacy of irregular middle?​

Correct option is C

Claim:"Sound is eternal (sādhya)."

Reason:"Because it is audible (hetu)."

Problem:

Audibility (being heard)does not inherently imply eternality(being timeless).

In Nyāya, eternality requires proof like"all-pervading"or"uncaused"—not mere perception.

Thehetu("audible") isillogically pairedwithsādhya("eternal").
