(C) The given quadratic equation is $k x^{2}-4 x-4=0$.Comparing this with the standard form $a x^{2}+b x+c=0$,we get $a=k$,$b=-4$,and $c=-4$.The discriminant $D$ is given by the formula $D = b^{2}-4ac$.Given that $D = 64$,we substitute the values into the formula:$64 = (-4)^{2}-4(k)(-4)$$64 = 16 + 16k$Subtract $16$ from both sides:$48 = 16k$Divide by $16$:$k = 3$.

If $64$ is the discriminant of $k x^{2}-4 x-4=0$,then the value of $k$ is ...........
