Correct Answer:
C. 3rd
According to IQAir's 2024 World Air Quality Report, Pakistan was ranked as the 3rd most polluted country globally. This ranking highlights the severe air quality challenges faced by Pakistan, primarily driven by factors such as industrial emissions, vehicular pollution, agricultural burning, and brick kilns. Poor air quality has significant adverse impacts on public health and the environment. Therefore, option C is accurate.
- Options A (1st), B (2nd), and D (4th) are incorrect. While Pakistan consistently ranks among the most polluted nations, the specific ranking for 2024 by IQAir was 3rd, with Bangladesh and India ranking 1st and 2nd, respectively.
