Which of the following is a characteristic trait of an Irish Stout?

The defining characteristic trait of an Irish Stout is its roasted malt flavors. This style of beer is typically brewed with dark roasted malts, which impart rich flavors of coffee, chocolate, and caramel. These roasted qualities contribute to the overall profile of an Irish Stout, setting it apart from other beer styles.

While some stouts may have a range of carbonation levels, Irish Stouts are generally known for their smooth and creamy mouthfeel, which is achieved through lower carbonation rather than high carbonation. The citrus hop aroma is more commonly associated with pale ales and IPAs rather than stouts, which typically have a more subdued hop character, focusing instead on malt flavors. Additionally, Irish Stouts usually have a medium to full body, rather than a light body, which enhances the richness of the beer. Thus, the emphasis on roasted malt flavors is what truly defines the style and makes it distinctive within the broad category of stouts.
