D. If both assertion and reason are false.

Answer

To solve the assertion and reason question regarding cannabinoids, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states: "Cannabinoids are drugs of abuse."
- **Explanation**: Cannabinoids are compounds found in the cannabis plant (Cannabis sativa). When consumed in excessive amounts, they can impair physical, psychological, and physiological functions, which qualifies them as drugs of abuse. Therefore, this assertion is **true**.

### Step 2: Analyze the Reason
The reason states: "They affect cardiovascular system and Central nervous system activity."
- **Explanation**: Cannabinoids interact with specific receptors in the brain and throughout the body, influencing both the central nervous system (CNS) and the cardiovascular system. This interaction can lead to various effects, including altered heart rate and changes in mood and perception. Thus, this reason is also **true**.

### Step 3: Determine the Relationship
Now we need to determine if the reason correctly explains the assertion.
- The assertion is that cannabinoids are drugs of abuse, and the reason explains that they affect the cardiovascular and central nervous systems. Since the effects on these systems can lead to impairment and abuse, the reason indeed supports the assertion.

### Conclusion
Both the assertion and the reason are true, and the reason is a correct explanation of the assertion. Therefore, the correct answer is that both statements are true, and the reason correctly explains the assertion.

### Final Answer
Both the assertion and the reason are true, and the reason is a correct explanation of the assertion.
