Step-by-step explanation:
The statement that is true about managing a supply chain is: Managing supply chains has become difficult over the years, as it involves working with a large number of organizations.
In the era of globalization and improved transportation and technology, managing supply chains has become more complex. As companies outsource and offshore their operations to access cheaper labor markets, they have to work with multiple organizations across different countries. This adds complexity to the supply chain management process.

Companies may hire outside firms for tasks like accounting, payroll, and data processing services. These changes have made managing supply chains more difficult.
