How can I move the point B to be a straight line?

In the photo, there were three points called A.B.C.
I want to move point B to be straight line with point A and point C.
Could any nice brother or sister could tell me how I can do this, please?
THANK YOU ALL OF YOU !!!

THANK YOU FOR RICHARD MARKLEW!!
THE PROBLEM IS SOLOVED.

Select points A and C.
Connect them - shortcut J
Subdivide this new line - W / Subdivide
Delete the original point B - X / delete vertex

Alternately…

Select points A and C. Shift S, pick move cursor to selection. (Moves cursor to the average of the selected vertices.) Deselect those. Then select point B. Shift S, pick move selection to cursor.

Since B should be moved on Z axis as in your image, select A,B,C and S-Z-0, scale Z zero.

That will, however, also move points A and C

select A,C press ctrl-alt-space, then shift-s cursor to selected, then set cursor as pivot point, then press s-shift-z-z-0

@Morio: Yes, you’re right. That moves AC however for 32 circle points error is negligible.
#2 is easiest but what if B is not in the middle? Is there any quick way of doing that?

Jump into ‘Vertex Snap’ mode [ctrl-shift-tab, 2], select point B, translate along the z axis [g, z], and snap to either points A or C by holding [ctrl] and clicking one of them.

There are so many different ways!
