A proper radiograph for showing upper and lower ribs would prominently feature Ribs 1-7, the true ribs, and Ribs 8-10, which are false ribs, thereby making Ribs 1-10 the correct answer for the radiograph in question.
The appropriate radiograph for displaying both upper and lower ribs would be one that includes Ribs 1-7, which are the true ribs, and Ribs 8-10, which are false ribs that attach via their costal cartilage to the cartilage of the next higher rib. Since Ribs 11-12 are floating ribs and do not have a direct or indirect attachment to the sternum, they will not be primarily featured for assessment in a radiograph intended to display ribs attached to the sternum.
Hence, the correct answer is Ribs 1-10. To ensure a comprehensive view, radiographs may slightly vary depending on the angle and purpose of the examination but typically Ribs 1-10 are considered key for a standard rib series X-ray.
