All factors remaining constant, which of the following set of exposure conditions would yield an image with the GREATEST radiographic film density?
A)100 mA, .75 sec, 40" SID, 70 kVp
B)150 mA, .25 sec, 44" SID, 80 kVp
C)300 mA, 125 ms, 40" SID, 70 kVp
D)400 mA, 187 ms, 56" SID, 88 kVp

The greatest radiographic film density is achieved by using the highest mA and the longest exposure time possible without exceeding the safe limits for the patient. Therefore, choice D with 400 mA and 187 ms has the highest mA and longest exposure time compared to the other choices, and thus, would yield the greatest radiographic film density. The SID and kVp also have an impact on image density, but in this case, they remain constant for all choices.
