Detailed Solution

The given statement is false.
No, the rays are not always parallel to the principal axis. For example, the Rays coming from an object at infinity are parallel to each other but not essentially parallel to the principal axis.
Light rays are never flawlessly parallel because the distance to their source point is always a fixed distance. So, in theory, if the distance travelled is nearly infinite, and the separation of the rays is close to zero, then we can call them parallel.
Therefore the correct statement would be that the rays coming from an object at infinity are parallel to each other but not essentially parallel to the principal axis.
