The correct answer is a. enamel.Enamel is the most mineralized tissue in the human body. It is the hard, outer surface layer of a tooth that is composed primarily of calcium and phosphate in the form of hydroxyapatite crystals. Enamel has the highest mineral content of any tissue in the body, with a mineral content of approximately 96-98%. This high mineral content gives enamel its hardness and resistance to wear and decay.The other options, such as cellular cementum, dentine, acellular cementum, and bone, are also mineralized tissues in the human body, but they have a lower mineral content compared to enamel. Cellular cementum and acellular cementum are specialized tissues found in the periodontium, while dentine is the tissue that makes up the bulk of a tooth's structure, located beneath the enamel. Bone, on the other hand, is a mineralized connective tissue that makes up the skeletal system and has a lower mineral content compared to enamel.
