Section 107, P.P.C. provides definition of

Section 107 of the P.P.C. provides the comprehensive definition of abetment. This foundational concept in criminal law outlines three distinct ways a person can abet the commission of an offence: by instigating a person, by engaging in a conspiracy, or by intentionally aiding the doing of a thing. Therefore, option C is the correct answer. Option A, 'Aggression', is a general term and not defined in this section. Option B, 'Instigation', is indeed one of the modes of abetment, but it is not the complete definition provided by Section 107; rather, it is a component of the broader concept of abetment.
