D) all of the above

In order to have the highest quality voice for a major speech, it is best to avoid smoking, screaming, and talking for a long period of time on the telephone.

Smoking can irritate and damage the vocal cords, leading to a hoarse or weak voice. Screaming puts strain on the vocal cords and can cause temporary or permanent damage. Talking for a long time on the telephone can also strain the voice, leading to fatigue and potential vocal problems during the speech.
