The Merino breed can be classified into what four distinct types?

The classification of the Merino breed into four distinct types focuses on the fineness and quality of the wool produced by these sheep. The correct classification includes superfine, fine, medium, and strong wool. This system is used to categorize the wool based on micron count, which is a critical factor in assessing wool quality.

Superfine wool is known for its softness and is often sought after in high-end textile markets. Fine wool follows, being slightly coarser but still considered high quality. Medium wool is typically used in a broader range of garments and has a longer staple length. Strong wool refers to the coarser category, often used for more durable wool products.

Understanding these classifications is essential because it not only helps in evaluating the wool's end-use but also plays a significant role in breeding decisions and marketing strategies for sheep producers. The other classifications presented do not align with the established terminology or grading systems recognized in the wool industry, making option B the most accurate and complete choice.
