I read it on the Kaplan step1 review book(vol.2).
"Concentration is ...usually tested by asking the patient to do mental arithmetic, e.g., serial subtraction of the number 7 from a given starting point of 100 or reporting events to which the interviewer has directed the patient (e.g., tap every time the interviewer says the letter "a")."
Hope this helps.

I agree with C as well. Because in the research that I am curently working we conduct patient's memory by asking them to substract 3 from 20 and keep on substracting like 17,14 and so on
