Final answer:
Option (B) Psychologists cannot write prescriptions for drugs, unlike psychiatrists who have the authority to prescribe medication.
Step-by-step explanation:
Psychologists cannot write prescriptions for drugs. While both psychologists and psychiatrists can conduct therapy and counseling, clinical psychologists have a PhD or a PsyD, whereas psychiatrists have a doctor of medicine degree (MD). Psychiatrists are medical doctors and as such, they have the authority to prescribe medications. Psychologists, however, focus on providing therapy and counseling services without prescribing medication.
