Answer:
B). To persuade readers that plastic bags negatively affect people and the environment.
Explanation:
Editorial Cartoons are described as the visual or graphic representation of the certain specific ideas, comments, or opinions of the creator that primarily intends to convey an implied social or political message for the audience.
In the given cartoon, the author's intent or purpose is to reveal a social message and 'convince the readers that plastic bags create a negative impact on people and the environment'. The use of phrase 'fall is in the air' for the 'blowing leaf' and 'so are few other things' for plastic bags implies the 'damaging' impact of plastic bags on surroundings. Thus, option B is the correct answer.
