Final answer:
A Greenfield investment refers to the establishment of completely new operations, such as constructing new facilities in a foreign country. It involves a substantial capital investment and is distinct from an acquisition, equity stake, full ownership, or joint venture.
Step-by-step explanation:
The term that refers to the startup of new operations is A. Greenfield investment. A Greenfield investment is when a company starts a new venture by constructing new facilities in a foreign country from the ground up. It typically involves significant capital investment and the creation of new jobs. Unlike other forms of investment, such as C. Acquisition (which refers to buying an existing company) or D. Equity stake (which means purchasing a part of a company), a Greenfield investment is focused on the establishment of entirely new operations.
Other terms like B. Full ownership refer to a situation where a company or an individual owns 100% of a business, and E. Joint venture refers to a business arrangement where two or more parties agree to pool their resources for the purpose of accomplishing a specific task, often the creation of a new business entity where both share risks and profits.
