    Find the values of the given polynomials at \[m=1,\] \[n=-2\] and \[p=3\] then match the following.
    Column - I Column - II
    I. \[{{m}^{3}}+{{n}^{3}}+{{p}^{3}}\] p. \[-5\]
    II. \[mn+np+pm\] q. 49
    III. \[{{m}^{3}}+{{n}^{3}}+{{p}^{3}}-3mnp\] r. 20
    IV. \[{{m}^{2}}{{n}^{2}}+{{n}^{2}}{{p}^{2}}+{{p}^{2}}{{m}^{2}}\] s. 38

    A)  \[(I)\to r,\,(II)\to q,\,(III)\to p,\,(IV)\to s\]

    B)  \[(I)\to s,\,(II)\to r,\,(III)\to q,\,(IV)\to p\]

    C)  \[(I)\to r,\,(II)\to p,\,(III)\to q,\,(IV)\to s\]
