The correct answer is: It adds half the value of the note or rest to the note or rest.

A dot (•) placed next to a note or rest in music notation signifies that half the value of the note or rest should be added to the original value. In other words, it extends the duration of the note or rest by half. So if a quarter note is dotted, it would have the value of a quarter note plus an eighth note. Similarly, if a rest is dotted, it would have the value of the rest plus an eighth rest.
