(C) The given quadratic equation is in the form $ax^{2}+bx+c=0$.Comparing $x^{2}-5x-14=0$ with the standard form,we get $a=1$,$b=-5$,and $c=-14$.The discriminant $D$ is given by the formula $D=b^{2}-4ac$.Substituting the values,we get $D=(-5)^{2}-4(1)(-14)$.$D=25+56$.$D=81$.Therefore,the discriminant is $81$.
