Final answer:
The argument mentioned employs a red herring fallacy by diverting the conversation to a different, tangentially related subject, thereby avoiding the main topic of discussion.The correct option is C.
Step-by-step explanation:
The type of logical fallacy being used in the argument you provided seems to align with a red herring fallacy. The red herring fallacy involves diverting the argument to a different subject that might seem related but is in fact a distraction from the original topic. It's a tactic that shifts the audience's focus to a new subject rather than addressing the argument at hand. For example, if someone argues that they need to exercise more and the response is to critique the feasibility of a particular type of exercise, such as cycling, without addressing the broader need for exercise, this is a red herring because it changes the subject rather than responding directly to the challenge of increasing exercise.
