Discussion
Assertion: a driver should be tested against a loopback before being used with real hardware. Reason: a loopback removes the external device as a source of doubt.
Answer: D
Correct answer: both the assertion and the reason are true and the reason explains the assertion
Both are true and the reason gives the mechanism. Connecting a peripheral’s output to its own input means the data returned is known, so a failure can only be in the driver or the peripheral configuration. Bringing in the real device adds its own wiring, timing and configuration as possible causes, and debugging several at once is far harder.
