Which of the following is true about Draft Horses?

Draft horses are indeed known for their heavy build and work capacity, which is the distinguishing characteristic that sets them apart from other horse breeds. These horses have powerful musculature and substantial bone structure, enabling them to perform hard labor such as pulling heavy loads, plowing fields, and participating in various agricultural activities. Their strength and size make them well-suited for tasks that require endurance and power, which is a fundamental aspect of their purpose.

The other options do not accurately reflect the nature of draft horses. They are not primarily used for racing; that is a characteristic of breeds specifically bred for speed. Their size is generally large and robust rather than small, and they are not primarily bred for show purposes, although they can also be seen in competitive shows related to strength and pulling capability. Understanding the specific qualities and typical use of draft horses provides essential knowledge for recognizing their unique role in agriculture and work contexts.
