Argument I: This argument is strong as it highlights that pollution can be controlled if there is awareness and cooperation among the public. It emphasizes the potential for change through collective effort.
Argument II: This argument points out the overwhelming factors contributing to pollution, such as crowded highways and industrial growth. While it may sound pessimistic, it does suggest that the current situation is difficult to manage, which reflects a realistic perspective on the challenges faced in controlling pollution.
Both arguments offer valid points about the situation regarding pollution.
So, the correct option is (C): If either I or II is strong.
