Solution

The correct option is C $t$
Since in a standard quadratic polynomial $x^{2} + x + a$ , $x$ is a variable and $a$ is a constant term, therefore, in the given polynomial $t^{2} + 4 t + 5$ we have variable $t$ and $5$ is a constant term.
Hence, the variable of the given quadratic polynomial is $t$ .
