To constitute a criminal conspiracy there must be an agreement of minimum

Foundational Concept: A conspiracy, by its very nature, requires a collective agreement, meaning more than one individual must be involved.

• Correct Option (C) Two or more persons: Section 120A P.P.C., which defines criminal conspiracy, explicitly states that there must be an agreement between "two or more persons." A single individual cannot form a conspiracy alone; it necessitates a meeting of minds.
• Distractor (A) Five or more persons: While a conspiracy can involve many individuals, five is not the minimum legal requirement.
• Distractor (B) Three or more persons: Similarly, three is not the minimum. The law sets the threshold at two.

Therefore, the essential element for constituting a criminal conspiracy is the agreement of at least two individuals.
