Two major new challenges related to the successful implementation of:. 1. cross-border teams are managing people you can’t see and redefining the role of management itself. 2. managing conflict and working in isolation. 3. supporting managers with appropriate IHRM strategies and rewarding performance. 4. managing communications in large teams and increasing diversity.

the correct answer option is b. a single paragraph.

explanation:

when you are thinking about paragraph​ topics, you should always choose a subject that can be adequately addressed in a single paragraph.
