Which of the following describes a significant feature of Brahman cattle?

Brahman cattle are recognized for their distinct physical characteristics, one of the most notable being their large, floppy ears. This feature is not just for aesthetics; the large ears help with heat regulation, allowing the cattle to remain cooler in hot climates. Brahman cattle are primarily adapted to warmer environments, and their ear size plays a vital role in dissipating heat.

In addition to their ears, Brahman cattle have many other unique traits that help them thrive in specific environments, such as their loose skin, which also aids cooling. While options like short tails and long legs may describe traits found in other cattle breeds, they are not defining features of Brahman cattle. Instead, the considerable size and shape of their ears stand out as one of the most recognizable traits in identifying the breed.
