Good job

The correct answer is C.

Oral cancers are highly associated with alcohol and tobacco use, and HPV-16 (human papilloma virus type 16, which is also found in cervical carcinomas) is found in nearly half of all oral cancers. The pattern of tumor development probably reflects exposure-related factors. Oral cancers develop in the following locations (in order of decreasing frequency): (1) floor of the mouth (choice C); (2) tip of the tongue (choice E); (3) hard palate (choice D); (4) base of the tongue (choice A); and (5) others (choice B).
