    Which of the following options hold?
    Statement - I: If p(x) and g(x) are two polynomials with \[g(x)\ne 0,\] then we can find polynomials q(x) and r(x) such that \[p(x)=g(x)\times q(x)+r(x),\] where degree of r(x) is greater than degree of g(x).
    Statement - II: When \[4{{x}^{5}}+3{{x}^{3}}+2{{x}^{2}}+8\] is divided by \[4{{x}^{2}}+2x+1,\] then degree of remainder is 1.

    A)  Both Statement - I and Statement - II are true.                          

    B)  Statement - I is true but Statement - II is false.                           

    C)  Statement - I is false but Statement - II is true.                            

    D)  Both Statement - I and Statement - II are false.                         

    Correct Answer: C

    Solution :

    Statement - I is false because if p(x) and g(x) are two polynomials with \[g(x)\ne 0,\]. then we can find polynomials q(x) and r(x) such that             \[p(x)=g(x)\times q(x)+r(x)\]   where \[r(x)=0\] or degree of \[r(x)\,\,<\] degree of g(x).         Statement - II is false as when \[4{{x}^{5}}+3{{x}^{3}}+2{{x}^{2}}+8\] is divided by \[4{{x}^{2}}+2x+1,\]the remainder is        \[-\frac{5x}{4}+\frac{31}{4}\]which is a polynomial of degree 1.
