Final answer:
Export, franchising, and foreign subsidiary are popular options for international entry.
Step-by-step explanation:
Out of the options listed - export, licensing, franchising, foreign subsidiary, and alliance and joint venture - export, franchising, and foreign subsidiary are among the most popular for international entry.
Export refers to selling products or services from one country to another. It is a common method for companies to enter international markets.
Franchising involves a business (franchisor) granting another party (franchisee) the rights to use its brand and replicated business model. This allows the franchisee to establish a business in a foreign market quickly.
Foreign subsidiary refers to establishing a separate legal entity in a foreign country. This allows the company to have a physical presence and more control over operations in the international market.
Licensing and alliance and joint venture are also popular options for international entry, but they may not be as widely used as export, franchising, and foreign subsidiary.
