Answer:
(c)-All results for the experimental groups involving wing surgery would be invalid.
Explanation:
The study researcher shown in the above question noted that flies that underwent wing surgery were more attacked than those that received no wing treatment. However, the researcher does not show the study variables and, consequently, does not show any relationship between the variables and the research result. For this reason, we can state that based on this result, all results for experimental groups involving wing surgery would be invalid.
