Answer 2

Answer: b. line

Step-by-step explanation:

We know that in geometry, there are three undefined terms and they are

1) point (no dimension)

2) line (one dimension)

3) plane (two dimension)

Therefore, from the given options the undefined term is 'line'.

In geometry a line is defined as a shape that is extending infinitely in two directions but has no width. It is one dimensional .
