Answer: Option 'C' is correct.
Step-by-step explanation:
We need to find which has one dimension.
Since Point is undefined term with no size or dimension, but in two dimensional it is found in ordered pair i.e. (x,y)
Plane is also an undefined term with length and width but no thickness, so, it is two dimensional.
Angle is undefined term formed by tow lines or rays diverging from a common vertex, so it is two-dimensional.
But Line is also undefined term with length only but there is no width or thickness.
So, Line has exactly one dimension.
Hence, Option 'C' is correct.
