Which of the following steps of inference as per classical Indian School of logic involve application of the universal concomitance to the particular present case
A. Socrates is mortal
B. Because he is a man
C. Whoever is a man is mortal e.g. Pythagoras
D. Socrates is a man who is invariably a mortal
E. Therefore Socrates is mortal
Choose the correct answer from the options given below:

Correct option is D

In classical Indian logic, the application of universal concomitance (vyapti) refers to establishing a universal relationship and applying it to a specific case. Step D involves this reasoning by asserting that Socrates, being a man, is invariably mortal, thereby applying the general rule of mortality to a specific individual.
Information Booster:
1. Universal Concomitance (Vyapti): The necessary relationship between the major term (mortality) and the middle term (man) is applied to the minor term (Socrates).
2. Indian Logic: This school of thought emphasizes the application of general rules (such as "all men are mortal") to specific instances.
3. Vyapti in Reasoning: Universal concomitance is a central concept in Indian inference, where it connects a general rule to particular cases.
4. Inference Process: Steps like C and D illustrate the formal structure of applying universal rules in classical Indian logic.
