Which of the following brands focuses strictly on offering polo shirts?

The answer highlighting Kiton reflects the brand’s reputation as a luxury Italian clothing manufacturer known for its high-quality menswear, including tailored clothing and fine knitwear. While Kiton produces a range of sophisticated garments, its focus on shirts, particularly polished and upscale styles like polo shirts, makes it a standout in this category.

In the context of the other brands, Kith is recognized for its streetwear aesthetics and wide range of casual apparel, but it does not specialize exclusively in polo shirts. Kjus is primarily known for its high-performance ski and golf apparel, making it more focused on functional activewear rather than classic polo designs. L.L. Bean, while offering a variety of casual clothing including polos, is distinguished for its outdoor and lifestyle focus rather than a strict emphasis solely on polo shirts. This understanding of each brand's core offerings clarifies why Kiton is the best answer regarding a focus specifically on polo shirts.
