In legal terms, what does the acronym IPC stand for?

The acronym IPC stands for Indian Penal Code. It is a comprehensive statute in Indian law that outlines various criminal offenses and their respective punishments. Enacted in 1860, the IPC serves as the cornerstone of criminal law in India, providing a common code that applies uniformly across the country. The code includes definitions of different crimes, including theft, murder, and assault, and establishes the legal framework for prosecuting criminal offenses.

The other options refer to terms that do not accurately represent a recognized or established body of law in the context of Indian legal framework, as there are no formal laws or codes known as the International Penal Code, Institution of Penal Code, or Interstate Penal Code in relation to criminal law in India. Thus, the Indian Penal Code stands as the correct answer due to its foundational role in the country's legal system.
