Sadhya probandum property – UGC NET Question

Sadhya is the property or fact that the arguer seeks to establish in the paksha by means of inference. In "the hill is fiery", 'fiery' is the sadhya whose presence is indicated by the hetu smoke. The entire inferential structure is oriented toward demonstrating this sadhya. Hence the property described in the stem is called sadhya.

Option A:
Option A, paksha, is the subject hill, the locus in which the sadhya is to be proved, and so cannot be identified with the property itself. They occupy different roles in the inferential triad.

Option B:
Option B, hetu, is the sign or reason, such as smoke, and serves as the evidential bridge to the sadhya rather than being the probandum.

Option C:
Option C is correct because sadhya literally means "that which is to be established" and captures the goal of the inferential process in Nyaya. Recognising sadhya clarifies what exactly the argument is trying to show.

Option D:
Option D, vyapti, denotes the universal concomitance between hetu and sadhya and is a relation, not a property located in the paksha.
