Which undefined term can contain parallel lines

Plane

Step-by-step explanation:

Undefined terms : The terms that is difficult be defined .

There are three undefined terms in geometry .

i)  A point helps to determine the exact position of a figure thus it has no dimension.

ii) A line is a one-dimensional geometric figure that extends upto infinity.

iii) A plane is a flat two-dimensional surface extending in all directions.

A plane can be determined by more than two lines or line and point not on that line.

Thus , the undefined term that can contain parallel lines = Plane

b is the right answer
