Answer:

d. nicotine

Step-by-step explanation:

Nicotine is the chemical in tobacco that makes tobacco addictive. Nicotine results in long-term brain changes creating addiction. Nicotine enters directly into blood stream and stimulates adrenal glands to release adrenaline (epinephrine) causing an increase in :

  • Blood pressure
  • Heart rate
  • Respiration

After entering the blood, it quickl enters the brainand triggers a cascade of biochemical reactions that are interpreted by the brain as rewarding.It is a legal drug too

Hence in the given scenario, Betty is probably addicted to Nicotine.
