Step 1: Understanding the fallacy.
This argument dismisses the uncle's opinion on off-shore drilling simply because of his association with an oil company, which is an example of the genetic fallacy.
Step 2: Analyzing the options.
- (A) Post Hoc: This fallacy assumes that because one event follows another, the first caused the second, which is not the case here.
- (B) Bandwagon: This fallacy assumes something is true because many people believe it. This is not the case here either.
- (C) Genetic Fallacy: This fallacy dismisses a claim or argument based on its origin or source rather than its merit. Here, the uncle's opinion is dismissed based on his job at an oil company.
- (D) Ad Hominem: While similar, an ad hominem attack directly targets a person's character rather than their argument, which is not exactly what is happening here.
- (E) Burden of Proof: This fallacy shifts the burden of proof to someone else. This does not apply in this case.
Step 3: Conclusion.
Option (C) is the correct answer as it directly addresses the flaw of dismissing an argument due to its origin or the background of the person making the claim.
