Verified step by step guidance

1. Step 1: Understand the term 'comorbidity' in the context of psychology, which refers to the occurrence of more than one disorder or illness in the same individual simultaneously.
2. Step 2: Review each option carefully to see which one aligns with this definition:
3. Step 3: The first option talks about inheritance, which relates to genetics, not comorbidity.
4. Step 4: The third option refers to diagnosing a single disorder, which does not capture the idea of multiple disorders occurring together.
5. Step 5: The fourth option describes the rate of occurrence of a disorder in a population, which is about prevalence, not comorbidity.
