Sesavat effect to cause inference – UGC NET Question

Sesavat anumana moves from the experience of a current effect to the conclusion that an appropriate cause must have occurred earlier. Seeing a swollen river and inferring that there has been heavy rain upstream exemplifies this pattern. The temporal direction is from later effect back to prior cause. Thus the type of inference described in the stem is sesavat.

Option A:
Option A is correct because sesavat traditionally stands for inference "like the remainder," where what is now present implies something previously existing that accounts for it. It captures the explanatory move from observed consequence to unobserved origin.

Option B:
Option B, purvavat, infers future effects from present causes and thus cannot represent the effect-to-cause reasoning at issue.

Option C:
Option C, samanyatodrsta, draws on general correlations not necessarily tied to a specific causal sequence, which is different from the cause–effect structure here.

Option D:
Option D, kevalavyatireki, concerns how vyapti is established (only through negative instances) and does not directly specify temporal direction.
