        A     B      C      D       f(output)
        0      0       0     0               0
      0     0        0    1`              1
        0      0       1    0                0

    avtually this can be implemented with a single MUX 8:1.
    but u have asked to implement this function with a4:1MUX.
    this is as shown below
                  
    here we have connected A(MSB) to enable pins of 2 MUX es.
    if A is 0 i.e, for 0,1,2,3 upper mux will be activated.
    and if A is high 1 down mux is activated.
    ok nice u go some much deep in these type really u canplay with STLD subject.
