Hint As we know that there are various animals, birds, insects, microorganisms on the earth. The tallest animal on the Earth is the Giraffe which is about 14 to 19 feet in standing position. Neck of a Giraffe can be up to 7 feet.
Complete step by step answer As we know that the Giraffe is the tallest known animal on the earth with the average standing height of about 14 to 19 feet. The lifespan of Giraffe is about 40 years. The neck of the Giraffe is its tallest body part which is about 7 feet. The evolution of Giraffes made its height so long. They eat the Leaves of Plants. Evolution theory says that the Giraffes height increased to this extent in hundreds of years of evolution. The height of elephants is generally 13 feet which is obviously less than the height of Giraffe so option B is the wrong answer. Camels and Buffalo’s height is also less than that of Giraffe. If we talk about birds, ostrich is the tallest bird. So the giraffe is the tallest animal.
Therefore, the correct option is option A.
Note As we know that the tallest animal on the earth is the giraffe. The average height of a standing giraffe varies from 14 feet to 19 feet while the average height of a standing elephant is about 13 feet. Clearly the tallest animal on the planet earth is the giraffe. The neck of a giraffe is the longest body part which is about 7 to 8 feet.
