Which of the following is not a light beer option listed?

Victory Sour Monkey is the correct choice as it is not categorized as a light beer. It is a Belgian-style sour ale that has a distinct profile and a higher alcohol content compared to the other options listed. Miller, Bud Light, and Michelob Ultra are all recognized as light beers, which are characterized by lower calorie counts and lower alcohol by volume. These beers are specifically brewed to appeal to those looking for lighter options, making them popular choices among light beer drinkers. Victory Sour Monkey, being a sour ale, does not fit into this light beer category, thereby making it the correct answer in this context.
