Answer choice B is incorrect because of the longer exposure time, the likelihood of motion artifact increases. An exposure of 90 mAs is usually acceptable for most patients. A desired exposure time is usually between 0.5 and 2 seconds. Shorter the exposure time, the greater the production of noise artifacts and grid lines. The longer the exposure time, the increased risk of motion and overexposure.
Answer choice C is incorrect because increasing mAs increases the radiation dose.
Answer choice E is incorrect because density refers to the blackness of an image. The degree of image blackness is directly related to the intensity of the radiation reaching the film or intensifying screen. Increasing mAs results in increase in density.
