Which of the following is not a branch of Commerce?

Computerisation is not a branch of commerce. Commerce refers to the exchange of goods and services, including all activities that facilitate trade, such as transportation, warehousing, and insurance. Computerisation, on the other hand, is a tool that can be used in many industries to automate processes and improve efficiency. While it may be relevant to commerce and trade, it is not considered a branch of commerce itself. Instead, it is a technological advancement that has been applied to many fields, including commerce, manufacturing, and service industries.
