Answer 1

Answer: (B)

Majority of mammals including human beings possess two sets of teeth during their life, a set of temporary milk or deciduous teeth replaced by a set of permanent or adult teeth. This type of dentition is called diphyodont. Human beings also have thecodont dentition, i.e., teeth are embedded in the sockets of the jaw bones
