A B or C?

added diagram for those who do not understand the question

I see three rotating pointers - A is rotating the slowest, at one rotation per second.

But all three pointers have the same rate of time, the second.

The angle of a pointer is not a measure of time unless it is calibrated against the second as a unit of time.

And your thoughts on the first diagram of cycles per second?

p.s I defined 1 second has the length/duration of the straight line under the diagrams that says 1.s at the end.

The question is simple and no other content is needed, evan managed a response to the simple question.

There is two diagrams with 3 points of measurement on each, all three points are measuring a rate per second, the line underneath each diagram is the length of the relative  second of the rate per second.

added - let me expand the question and add Minkowski's space-time and two measuring devices .

Which one of these clocks has a shorter second?
