Which of the following states has commercial casinos?

Nevada is known for its well-established legal framework surrounding commercial casinos, making it a leading state in the gambling industry. Las Vegas, in particular, is famous for its vibrant casino culture, attracting millions of tourists each year. Commercial casinos in Nevada offer a wide range of gaming options, entertainment, dining, and lodging, contributing significantly to the state's economy.

In contrast, states like South Carolina and Utah have strict laws against gambling, with no commercial casinos legally operating. Idaho allows certain types of gambling, such as lotteries and some forms of riverboat or tribal gaming, but it does not have the extensive commercial casino framework seen in Nevada. Therefore, Nevada stands out as the only option among the choices given that has a robust presence of commercial casinos.
