Which test execution schedule meets the test plan requirements and logical dependencies?

Your task is to compile a test execution schedule for the current release of software.

The system specification states the following logical dependencies:

– An admin user must create/amend/delete a standard user.

– A standard user is necessary to perform all other actions.

The test plan requires that re-tests must be performed first, followed by the highest priority tests. To save time, the test plan states that tests should be scheduled to create test data for the subsequent tests in the schedule.

The following test cases have been designed, with an indication of priority (1 being the highest priority) and whether the test has previously failed.

Which test execution schedule meets the test plan requirements and logical dependencies?
A . a, d, c, b, e
B . a, c, b, d, e
C . e, a, b, c, d
D . e, a, d, c, b
