### Solution:

The given points are,
$A\left(1,1\right),B\left(1,0\right),C\left(0,1\right),D\left(0,0\right),E\left(0,1\right),F\left(1,0\right),G\left(0,5\right),H\left(7,0\right),I\left(3,3\right)$.
If a point is on $y$-axis, then the coordinate of that point should be zero.
By observing the given point for the above condition,
The $x$-coordinate is zero at: $C\left(0,1\right)$, $D\left(0,0\right)$, $E\left(0,1\right)$ and $G\left(0,5\right)$.
Therefore, these points lies on the $y$-axis.
Hence, option is correct.
