Which of the following best illustrates the effectiveness of consumption subsidies in addressing positive externalities?

Consumption subsidies are financial support given by the government to encourage people to buy certain products or services that have benefits for society, known as positive externalities. For example, when the government provides a subsidy for electric cars, it makes them cheaper for consumers, which can lead to more people buying them. This is effective because electric cars reduce pollution and help fight climate change, benefiting everyone, not just the car owners. By making these cars more affordable, the subsidy increases their use, leading to a cleaner environment. Thus, consumption subsidies help promote goods that are good for society, addressing the positive effects they bring.
