The correct answer is option 3: Second incisor. In elephants, the tusk is actually a modified version of one of their incisor teeth. Incisors are the sharp, front teeth used for biting and cutting, and elephants have two sets of incisors on each side of their upper jaw. The second incisors are the ones that develop into tusks in male and some female elephants. These incisors continue to grow throughout the elephant`s life, and can grow to be several meters long. They are made of ivory, which is a type of dense, hard, and durable material. The tusks are used for a variety of purposes, including digging, lifting objects, and defending against predators.
