A user complains that his new mouse doesn't work right. He has an old system at home and when he has had this problem, he cleaned the ball on the underside of the mouse to fix it, but this mouse doesn't have a ball on the underside. What can you tell him about his mouse?

A) the ball must have fallen out
B) the ball is hidden under an access panel on new mice
C) the mouse is an optical mouse
D) the mouse uses sonar to detect movement

the mouse is an optical mouse

Explanation:

The user's mouse does not have a ball to be cleaned when it does not work right because he or she is using an optical mouse. This type of mouse does not use the old-ball-system, but rather uses a light source, which usually consist of a light detector and a light-emitting diode, and this set-up ensures that movement is detected relative to a surface and hence the cursor is moved too.
