Which statement about HVL and higher kVp is true?

Explanation:
HVL is a measure of beam quality, reflecting how penetrating the X-ray beam is. When you increase the kilovoltage peak, the X-ray spectrum shifts toward higher-energy photons, making the beam harder and more penetrating. With the same filtration, a thicker absorber is required to cut the beam’s intensity in half, so the half-value layer increases. Therefore, higher kVp leads to a larger HVL. The other options would imply no change, a decrease, or random fluctuations, which don’t match how beam hardening works with energy spectra.
