Which of the following is a trait of a Munich Helles?

A Munich Helles is characterized by a light body and a crisp finish, making it a refreshing lager that is easy to drink. This style originated in Munich, Germany, and is designed to be a pale malt-forward beer, balancing sweetness with a smooth mouthfeel. The beer typically has a moderate level of carbonation, contributing to its refreshing qualities, and is golden in color.

The other traits presented in the choices do not align with the characteristics of a Munich Helles. High bitterness and floral aroma are more commonly associated with styles like IPAs, while dark color and roasted flavors are indicative of darker beers like stouts or porters. A very sour taste with low carbonation describes sour ales or lambics, which also fall outside the spectrum of a Munich Helles. Therefore, the light body and crisp finish correctly represent the defining traits of this specific beer style.
