If only some keyboard keys are not working, what is the most appropriate initial conclusion?

Answer and explanation

Correct answer: The keyboard may have dust, physical damage, or a key-setting issue

The governing concept is symptom-based troubleshooting. When only a few keys fail, the first checks should focus on the keyboard itself: dust under the keys, liquid or physical damage, a loose connection, or an accessibility and layout setting. Option B is the most appropriate initial conclusion, but it is not proof of one exact fault. A complete operating-system failure, hard-disk damage, or monitor resolution would not usually affect only selected keys.
