Answer: its always

Step-by-step explanation:

If a point lies  in between  two end points of a line then the sum of distance between the points in between is always equal to the whole line.

If A is in between two points B and C then the sum of line segments BA and AC will always equal to the length of BC.

Or BA+AC=BC in all cases whatever be the position of point A between the points Band C.

Always is the right option.
