    Answer: b As anxiety increases, so does the heart rate. This is the body's natural response to danger. Anxiety increase the force of each beat and elevates the heart rate. When anxiety decreases, so does the heart rate. In this way the heart rate is an accurate index or measure of the anxiety a person is experiencing.
