The rules and regulations guiding the conduct of business transactions are known as law

In the context of **business transactions**, the rules and regulations that govern them are primarily known as **commercial law**. This is because **commercial law deals specifically with the legal aspects of business and trade**, and it includes a variety of laws that regulate how businesses operate, how they interact with other businesses, and how consumers are protected in these transactions.

Other laws mentioned, such as:

• Criminal law: Generally pertains to crimes and legal penalties for offenses against the state or public, rather than specific business transactions.
• Common law: Represents a body of unwritten laws based on legal precedents and is applicable in judicial decisions but is not specific to business laws.
• Contract law: Governs agreements between parties but is a subset of commercial law, specifically focusing on agreements and obligations within a business context.

Therefore, when discussing the guidelines and frameworks for business transactions specifically, **commercial law** is the umbrella under which these rules and regulations fall.
