Correct Answer. B.

Checking for visible damage or bends in the cable that could break internal wiring is a crucial first step in troubleshooting.
Option A is incorrect because the wattage rating of the adapter is unrelated to a sudden stop in charging unless the adapter has failed entirely.
Option C is incorrect because the color of the cable insulation is purely aesthetic and has no bearing on functionality.
Option D is incorrect because while extremely long cables can sometimes reduce charging efficiency due to voltage drop, they would not cause charging to suddenly stop unless damaged.
