D. If both As and R are wrong.

Answer

To analyze the given statements, we will break down the assertion and the reason step by step.

### Step 1: Analyze the Assertion
The assertion states: "Air pollutants are always gaseous."

- This statement is **incorrect**. Air pollutants can be in various forms, including gases, solid particles (like dust and soot), and liquid droplets (like aerosols). Therefore, it is not accurate to say that air pollutants are always gaseous.

### Step 2: Analyze the Reason
The reason states: "Ultraviolet rays do not cause any harm to human beings."

- This statement is also **incorrect**. Ultraviolet (UV) rays are known to cause harm to human beings. They can lead to skin damage, including skin cancer, and other health issues such as skin allergies. The ozone layer plays a critical role in protecting us from harmful UV radiation.

### Step 3: Conclusion
Since both the assertion and the reason are incorrect, we can conclude that the correct option is: **Both assertion and reason are wrong.**

### Final Answer
Both assertion and reason are incorrect.
