Here's why:
* Hornless: While Highland cattle typically have horns, there is a polled variety, meaning they are naturally hornless.
* Shaggy black coat: Highland cattle are known for their long, shaggy coats that come in various shades, including black.
* Bred for beef: Highland cattle are a beef breed, valued for their rich, flavorful meat.
While other breeds might share some characteristics, the combination of a hornless variety, a shaggy black coat, and beef production makes Highland cattle the most likely answer.
