(D) The logarithmic function $y = \log_a x$ is defined under the following conditions:$1$. The base $a$ must be a positive real number,i.e.,$a > 0$.$2$. The base $a$ cannot be equal to $1$,i.e.,$a 
eq 1$.$3$. The argument $x$ must be positive,i.e.,$x > 0$.Therefore,for the expression to be defined,$a$ must be any positive real number except $1$.

For $y = \log_a x$ to be defined,$a$ must be:
