Answer: First and Fifth are correct options.
Step-by-step explanation:
We need to find which is one dimensional and have infinite length.
Since we know about :
1 ) Ray which is defined as the portion of line which starts at a point but can extend to any limit from one side.
So, it has one end point and it is one dimensional and have infinite length.
2) Line which is defined as a straight extend from both the sides to any limit.
And it is one dimensional and have infinite length.
But the remaining options are neither one dimensional nor have infinite length.
Hence, First and Fifth are correct options.
