• A. Genetic studies have shown that bipolar disorder has a significant hereditary component.
• B. Biological research has found no evidence of neurotransmitter involvement in bipolar disorder.

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the context of the question, which is about biological research findings related to bipolar disorder.
2. Step 2: Review the role of genetics in bipolar disorder, noting that genetic studies have consistently shown a significant hereditary component, making this statement true.
3. Step 3: Consider neuroimaging research findings, which often reveal structural and functional brain differences in individuals with bipolar disorder compared to healthy controls, confirming this statement as true.
4. Step 4: Examine the involvement of neurotransmitters such as dopamine and serotonin, which research suggests are indeed implicated in bipolar disorder, supporting the truth of this statement.
5. Step 5: Identify the false statement by recognizing that biological research has found evidence of neurotransmitter involvement, so the claim that there is no evidence is false.
