Final answer:
The genus Musca provides the greatest amount of detailed information about the common house fly from the options given.
Step-by-step explanation:
When attempting to gain the greatest amount of detailed information about the common house fly, taxonomic classification is key. The most specific option listed is c. genus Musca.
Taxonomic classification goes from broad to specific as follows: phylum, class, order, family, genus, and species. The genus Musca provides information specific to the type of house fly, whereas classifications such as order Diptera or class Hexapoda include a far wider range of organisms, providing less detail about the specific habits, physiology, and characteristics of the house fly. Utilizing taxonomic keys or scientific literature at the genus level allows for a detailed understanding of the organism's traits and its position within the broader classification system.
