X-rays have the ability to penetrate various types of materials to different extents. The correct answer is that metal can be penetrated by x-rays, but the extent of penetration depends on several factors, including the thickness and density of the metal and the energy of the x-rays used. For instance, lower energy x-rays may have difficulty penetrating denser metals like lead, while higher energy x-rays can penetrate more effectively through various metals.

Thus, the statement that metal can be penetrated by x-rays is true, though it is essential to consider that not all metals will allow similar levels of penetration, which is where the nuances of the options come into play. Factors such as the type of metal and its thickness play a significant role in the decision-making process for radiological examinations involving metallic materials.
