To detect information about water flow, fish have sensors running from the snout tip down the sides of the head. Yuzo R. Yanagisuru, Otar Akanyeti, and James C. Liao conducted tests to find where the difference in pressure is greatest between two adjacent sensors because, according to the researchers, as these pressure differences increase, so does the amount of information available to the fish. Using the ratio of head width to length, they found that the greatest pressure difference is closer to the snout for narrower heads (lower ratio of width to length) and farther from the snout for wider heads (higher ratio of width to length). Based on this finding, a second team of researchers has hypothesized that the sensors where information is greatest are likely more sensitive than the rest.
Which finding, if true, would most directly support the second research team's hypothesis?
The longnose gar (Lepisosteus osseus) has a much narrower head than the devil catfish (Bagarius bagarius), and the most sensitive sensors of the longnose gar are closer to the snout than are those of the devil catfish.
A
The longnose gar (Lepisosteus osseus) has a much narrower head than the devil catfish (Bagarius bagarius), and the most sensitive sensors for both are very close to their snouts.
B
The longnose gar (Lepisosteus osseus) has a much narrower head than the devil catfish (Bagarius bagarius), and while the sensors nearest the snout for the longnose gar are more sensitive than the others, for the devil catfish all sensors are equally sensitive.
C
The longnose gar (Lepisosteus osseus) has a much narrower head than the devil catfish (Bagarius bagarius), and the most sensitive sensors for the devil catfish are closer to the snout than are those for the longnose gar.
