Explanation:

The word in the blank should form a term related to disease or harm in the host context. "pathology" means the study of diseases, and "path" as a prefix (path -) relates to disease. The other options: "bio" would form "biology" (study of life, not about harm), "techn" would form "technology" (unrelated to host harm). So "path" is the correct choice to fill the blank to make "pathology".
