Final answer:
A multinational enterprise exploring new methods for hiring and retaining multilingual managers for expatriate assignments is participating in talent management (option b), which is key to their success in global operations.
Step-by-step explanation:
A multinational enterprise (MNE) that is exploring new methods for hiring and retaining multilingual managers for expatriate assignments is participating in talent management. This process involves strategies and practices to recruit, develop, and retain highly skilled workers. As MNEs operate in various countries, talent management becomes crucial for their success to ensure they have the right personnel capable of handling diverse cultural and linguistic challenges.
The options given represent different strategic approaches for managing and staffing subsidiaries in foreign countries: polycentric, ethnocentric, and geocentric. However, these approaches are specific to the staffing strategies of MNEs and do not encapsulate the broader practice of hiring and retention, which is covered by talent management.
