Tests have been specified for the latest software release and users have prioritised these.
However, there are some dependencies between tests as shown in the table below (e.g. Test ID. '123' cannot be run until Test ID. '456' has been successfully completed).

Which test execution schedule best meets the prioritisation and dependency conditions?

• A.6, 1, 2, 9, 4, 3, 5, 7, 8, 10.
• B.3, 5, 7, 10, 2, 4, 6, 8, 9, 1.
• C.5, 7, 4, 3, 9, 10, 1, 6, 8, 2.
