Option 4 : (B), (C) and (D) only 

The major premise, minor premise, and conclusion make up an inference. 

• In Vyapti, the cause must be acknowledged to be inextricably linked to the predicate.
• The Logical substrate of inference is the universal relationship between reason and predicate.
• There can be no inference (Anumana) unless there is an invariable concomitance (Vyapti) between the mark and the character inferred Vyapti between the middle and major terms. 
• The Nya̅ya system theory of causation is ‘astkāryavāda’ or ‘ārmbhavāda’.
• Nya̅ya system introduced the notion of real universals or class character

Thus, Species - genus relation, causal relation, member-class relation type of relations are considered by the Nya̅ya system as necessary relations between middle and major terms.

•  In the theory of causation, there are two important components.
• The first is 'cause,' while the second is 'effect.'
