For $\Large a=0,~ \color{forestgreen}{\dfrac{a}{a}}$ is undefined. While for $\Large a\neq 0, \color{forestgreen}{\dfrac{a}{a}}$ is 1. Hence the correct option is

$\color{goldenrod}{\text{There is no fixed value.}}$

But "None of the choices" is a choice. Thus creating a rip in the spacetime continuum.

Yeah... exactly... Nice observation... We are actually selecting one choice instead of the fact that the correct answer is ' $None$ of the choices'.

'None of the other choices' will do.

Thanks, i have edited the choices so that there is no "rip in the spacetime continuum."

If $a$ is a real number, the the value of $\dfrac aa$ is always equal to $1$ , for all reals except $0$ , because when you substitute $a=0$ we get: $\dfrac 00$ which is not defined. Hence the answer is None of the above.
