Which of the following beers is a light beer?

The choice of Corona Light as a light beer is accurate because it is specifically brewed with fewer calories and lower alcohol content compared to its regular counterpart, Corona. Light beers are designed for those who prefer a less robust flavor profile and a lighter body while still enjoying the essence of beer. They often contain a lower carbohydrate content, making them a popular choice for drinkers looking to enjoy a refreshing beverage without the heaviness often associated with standard beers.

In contrast, while Heineken, Modelo, and Bud Light are well-known beers, they do not fit the description of light beer in the same way. Heineken is a standard lager with a traditional flavor and calorie content, while Modelo is a full-bodied pilsner that offers stronger taste notes. Bud Light is indeed a light beer, but the clear designation of Corona Light emphasizes its specific branding as a lighter option within its product line. This context helps to differentiate the specific characteristics of light beers and why Corona Light stands out in this question.
