The correct answer is: B. Antlers : Stag
Horns are a pair of hard, pointed projections that grow on the head of some animals, such as bulls, cows, and goats. Antlers are a pair of branched bony projections that grow on the head of some male deer, such as stags and reindeer. Both horns and antlers are used for protection, fighting, and display.
Manes are long, flowing hair that grows on the neck of some animals, such as lions, horses, and zebras. Hoofs are hard, hoof-like structures that grow on the feet of some animals, such as horses, cows, and pigs. Wattles are fleshy, dangling appendages that grow on the neck of some animals, such as turkeys and chickens.
Of the four options, only antlers and horns are used for protection, fighting, and display. Mane, hooves, and wattles are not used for these purposes.
