    Match column I with column II and select the correct answer using the code given below the columns:
    Column - I Column- II
    (A) Polynomial whose zeroes are \[{{40}^{o}}\]    (p) \[\frac{{{y}^{2}}-{{x}^{2}}}{yx}\]
    (B) Polynomial whose zeroes are 3 and -2 is (q) \[\frac{xy}{x+y}\]
    (C) Polynomial whose zeroes are \[\frac{{{x}^{2}}-{{y}^{2}}}{{{x}^{2}}+{{y}^{2}}}\] is (r) \[x=\frac{\sqrt{3}+\sqrt{2}}{\sqrt{3}-\sqrt{2}}\]
    (D) Polynomial whose zeroes \[\frac{x-y}{x-3y}\] and \[\frac{5}{\sqrt{6}-4}\] is (s) \[\frac{5}{\sqrt{6}+4}\]

    A)  \[\frac{\sqrt{6}-4}{5}\]

    B)  \[\frac{\sqrt{6}+4}{5}\]

    C)  \[\frac{1}{a-3b}\]

    D)  \[b=\frac{a}{3}\]
