Select the diagram that shows the line through $E$E and $F$F:

The image shows a straight line with arrows at both ends, indicating that it extends infinitely in both directions passing through the points F and G on the line, characteristic of a geometric line. There are three labeled points on this image: point E, point F, and point G. Point F and point G is marked with a dot on the line, and point E is marked with a dot but is not directly on the line, suggesting it is not collinear with points F and G.

A

The image shows a straight line with dots at both ends, indicating that the line starts from point E and stops at point F on the line, characteristic of a geometric segment. There are three labeled points on this image: point E, point F, and point G. Point E and point F is marked with a dot on the segment, and point G is marked with a dot but is not directly on the segment, suggesting it is not collinear with points E and F.

B

The image shows a straight line with arrows at both ends, indicating that it extends infinitely in both directions passing through the points E and F on the line, characteristic of a geometric line. There are three labeled points on this image: point E, point F, and point G. Point E and point F is marked with a dot on the line, and point G is marked with a dot but is not directly on the line, suggesting it is not collinear with points E and F.

C

The image shows a straight line with dots at both ends, indicating that the line starts from point E and stops at point G on the line, characteristic of a geometric segment. There are three labeled points on this image: point E, point F, and point G. Point E and point G is marked with a dot on the segment, and point F is marked with a dot but is not directly on the segment, suggesting it is not collinear with points E and G.

D

The image shows a straight line with an arrow at one end, indicating that it extends infinitely in one direction starting from point F passing through point E on the line, characteristic of a geometric ray. There are three labeled points on this image: point E, point F, and point G. Point E and point F is marked with a dot on the ray, and point G is marked with a dot but is not directly on the ray, suggesting it is not collinear with points E and F.

E

The image shows a straight line with an arrow at one end, indicating that it extends infinitely in one direction starting from point F passing through point G on the line, characteristic of a geometric ray. There are three labeled points on this image: point E, point F, and point G. Point F and point G is marked with a dot on the ray, and point E is marked with a dot but is not directly on the ray, suggesting it is not collinear with points F and G.
