What categories of clothing does Duckworth produce?

The correct answer highlights the specific focus of Duckworth as a brand that specializes in producing high-quality outerwear and knitwear garments. Duckworth is known for its dedication to using natural materials, particularly focusing on merino wool, which excels in creating functional and stylish sweaters and hoodies.

Outerwear encompasses a range of clothing designed to provide warmth and protection from the elements, which aligns with Duckworth's offerings. The inclusion of sweaters and hoodies further confirms the brand’s commitment to comfortable, durable clothing suited for outdoor activities and casual wear. Thus, the choice accurately reflects the niche that Duckworth occupies within the clothing market.

The other categories listed in the other choices do not encompass the primary focus of Duckworth’s product line, demonstrating why those options are not correct. For example, T-shirts and casual shirts are typically staples of a broader casual wear brand, while pants, dresses, and jeans pertain to different clothing segments that are not Duckworth's signature products.
