Detailed explanation-1: -The correct option is B ameloblast, odontoblast. Enamel is the outermost layer of teeth. It is the hardest substance of the human body. It forms the crown part of the teeth. It is formed by ameloblast cells.
Detailed explanation-2: -Functional ameloblasts are tall, columnar, polarized cells that synthesize and secrete a number of enamel-specific proteins. After depositing the full thickness of enamel matrix, ameloblasts shrink in size and regulate enamel maturation.
Detailed explanation-3: -Tooth enamel is formed by epithelially-derived cells called ameloblasts, while the pulp dentin complex is formed by the dental mesenchyme. These tissues differentiate with reciprocal signaling interactions to form a mature tooth.
