Final answer:
X-rays can be attenuated and ionized.
Step-by-step explanation:
In the context of x-rays, Attenuation refers to the reduction in the intensity of the x-ray beam as it passes through a material. When x-rays interact with matter, they can be scattered or absorbed. X-rays can be attenuated by both mechanisms. Compaction and subduction are not terms typically used to describe the interaction of x-rays with matter.
Ionization refers to the process by which x-rays can remove an electron from an atom, resulting in the formation of positively charged ions. This occurs when x-rays transfer sufficient energy to atoms as they pass through matter.
So, the correct answer would be: a.) Attenuated and c.) Ionized.
