Which of the following brands predominantly offers polo shirts?

The identification of Viyella as a brand that predominantly offers polo shirts is accurate, as this brand is well-known for its focus on traditional and classic menswear, which includes a significant range of polo shirts crafted from high-quality materials. Viyella has a reputation for producing stylish and durable polos that reflect a classic British aesthetic, thus making it a preferred choice for consumers looking for refined and comfortable polo options.

While the other brands also produce a variety of clothing items, they are not predominantly known for their polo shirt offerings. Versace leans more towards high-fashion items characterized by bold prints and luxury designs, whereas Vuori specializes in activewear, focusing on athletic and performance-oriented clothing. Vetements, on the other hand, is recognized for its avant-garde style and streetwear influence, often veering away from traditional polo styles. Therefore, Viyella's main focus on polo shirts makes it the correct choice in this context.
