The diagram shown here represents a) two intersecting lines. b) two intersecting planes. c) a line intersecting a plane in one point. d) two intersecting lines contained in a plane.

 B) two intersecting planes.

Step-by-step explanation:

Definitions:

A line is a one -dimensional geometric figure that extends infinitely in both directions. It has only length but no width.

The intersection of two line is a point.

A plane is a two dimensional flat surface (like a sheet of paper)  and it extends infinitely . It has both length and width .

The intersection of two plane is a line.

By considering the given figure , we can easily see that the two planes ( ∵they have both length and width) are intersecting each other and the intersection is a line.

It means the correct answer regarding the given diagram : B) two intersecting planes.
