Geometry

The possible name of the line is A.line AF.

Here's an explanation for each option:

A.line AF: A line can be named using any two points on the line. Since points A and F are on the given line, naming it line AF is correct.

B.line A: A line requires at least two points to be named properly. A single point like A cannot be used to name a line, so this is incorrect.
