Which of the following breeds is known for its muscle characteristics and originated in England?

The Suffolk breed is renowned for its muscular characteristics, making it particularly valued in the production of high-quality lamb meat. Originating in England, the Suffolk has a distinctive appearance, featuring a black face and legs, which sets it apart from other breeds. This breed's impressive muscle development contributes to its ability to yield a substantial amount of meat, which is a significant factor for farmers and breeders focused on market demand. Additionally, Suffolks are known for their adaptability to various farming conditions and their efficient growth rates, making them a favorite among sheep producers.

The other breeds listed, while they each have their unique attributes, do not share the same level of emphasis on muscle characteristics as the Suffolk. For instance, the Dorper is known for its hardiness and adaptability but was developed primarily in South Africa. The Romney is recognized for its wool and is primarily raised for wool production rather than meat. The Columbia is a dual-purpose breed with both wool and meat qualities but does not match the muscularity that defines the Suffolk. Thus, the Suffolk stands out when considering muscle development, particularly within the context of its English origins.
