Which of the following is used to control the degree of penetration of the x-ray beam?

Explanation:
Penetration of the X-ray beam is determined by beam quality—the energy of the photons produced. That energy is set by kilovoltage peak. Higher kVp increases photon energy, making the beam more penetrating so it can pass through denser tissues. Lower kVp reduces penetration and changes how the tissue differences are represented in the image. The amount of X-rays produced, which affects image brightness, is controlled by mA and exposure time, not how penetrating the beam is. Focal spot size influences image sharpness rather than penetration.
