In a competitive market, if a tax is imposed on a good, which of the following statements is true regarding consumer surplus and deadweight loss?

When a tax is imposed on a good in a competitive market, consumer surplus usually decreases. Consumer surplus is the difference between what consumers are willing to pay and what they actually pay. With the tax, the price consumers face increases, making them less willing to buy the good, which reduces their overall benefit. Additionally, a deadweight loss occurs because the tax discourages some transactions that would have happened without the tax. For example, if a tax is placed on a popular snack, fewer people might buy it because it costs more, leading to lost sales and a decrease in both consumer surplus and overall market efficiency.
