    Match the following.
    Column - I Column - II
    (p) If\[f(x)={{x}^{3}}-6{{x}^{2}}+11x-6,\] then \[f(-1)=\_\_\_.\] (i) \[-210\]
    (q) If \[f(x)=2{{x}^{3}}-13{{x}^{2}}+17x+12,\]then \[f(-3)=\_\_\_\_.\] (ii) 1
    (r) if \[x=\frac{4}{3}\]is a root of \[f(x)=6{{x}^{3}}-11{{x}^{2}}+kx-20,\]then \[k=\_\_\_\_.\] (iii) \[-24\]
    (s) If \[x=-1\]is a root of \[f(x)={{x}^{100}}+2{{x}^{99}}+k,\]then \[k=\_\_\_.\] (iv) 19

    A)             \[(p)\to (iii);(q)\to (iv);(r)\to (i);(s)\to (ii)\]

    B)        \[(p)\to (ii);(q)\to (iv);(r)\to (i);(s)\to (iii)\]
