Explanation

During a visual inspection of an embedded battery, technicians check for dot imprints (B) - small indentations that can indicate abnormal pressure or contact damage on the battery cells - and scratches (D), which signal physical damage that may compromise battery integrity or safety. Both are observable defects that a trained eye can catch without any tools beyond a visual check.

Why the distractors are wrong:

• A (Updated battery firmware): Firmware is software - it cannot be seen; you'd check it via diagnostics, not visual inspection.
• C (Correct color): Battery color is not a defined inspection criterion in Apple's service procedures; batteries don't vary in color to signal a problem.
• E (Battery-compliance shipping label): This label is a transportation/regulatory requirement for hazmat shipping, not an inspection point during an in-device repair.

Memory tip: Think "visible physical damage only" - if you can't see it with your eyes during a bench inspection, it's not a visual inspection item. Dot imprints and scratches are both surface-level, eye-detectable clues that something physically went wrong with the battery.
