Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Why wrong: A faulty battery management system could cause overheating, but the pad working with another phone points to an external factor like the case.
B
The phone's wireless charging coil is misaligned with the pad.
Why wrong: Misalignment would prevent charging from the start, not after a few minutes.
C
The phone case contains metal or magnetic components that interfere with charging.
This is correct; metal can cause eddy currents, leading to heat and charging interruption.
D
The wireless charging pad is not Qi-certified.
Why wrong: If the pad works with another phone, certification is not the issue; the problem is specific to this phone.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
