    Explanation:

    Total 12 such number can be generated as

    2! x 3! (because hundred digit can be either 1 or 2 while the unith and tenth digit can be any remaining numbers )

    = 2 X 6 = 12

    Number starting from 1 = 123,125,132,135,152 and 153.

    Number starting from 2= 213,215,231,235,251 and 253

    Hence, option 4 is the correct answer.
