Answer -
d

The kVp (kilo-volt peak) and mAs (milliamperage - second) are usual modes to control the presentation of radiographic image.
kVp is associated with ' radiographic contrast' and increasing it decreases the contrast and vice versa.
mAs usually is indicator of ' density' of the film. kVp also affects density but indirectly.
