The tallest animal can grow up to 5.5 metres. What is it?

The giraffe is the tallest land animal, capable of growing up to 5.5-6 meters in height. Their exceptionally long necks allow them to reach leaves on tall acacia trees that other animals cannot access. Giraffes are native to African savannas and woodlands. Their height is primarily due to their elongated neck vertebrae, not their legs. Option C has a spelling error ('Girrafe' should be 'Giraffe').
