Explanation

Option D is correct because asking whether the issue occurs with all SD cards or just this one isolates the problem to hardware vs. the specific card - if other cards work fine, the card itself is faulty; if no SD card is recognized, the MacBook's built-in SD card reader is the likely culprit. Option A (file types) is irrelevant at this stage - the card isn't even mounting, so the application never sees any files. Option B (Photos version) points to software, but the question specifically asks how to isolate the issue to hardware, making software questions out of scope. Option C (SMC/NVRAM reset) jumps straight to a fix before the problem is even diagnosed, which violates proper troubleshooting methodology. A helpful memory tip: in hardware troubleshooting, always swap the component - test a different SD card to determine whether the problem follows the card or stays with the machine.
