00:00Question says which of the following is multiplicative identity A0, B1, C2, D, X is 0 is the additive
00:20identity and 1 is the multiplicative identity means when we will multiply 1 with any number
00:29then it will be not 1 but that number for example 10 multiplied with 1 it will be 10 or 500 is
00:41multiplied with 1 it will be 500 so the correct option will be B1 1 is the multiplicative identity
