Final answer:
The fallacy involving attacks on the person rather than the argument is the Ad Hominem fallacy.
Step-by-step explanation:
The fallacy that involves attacking the person making the argument rather than addressing the argument itself is known as an Ad Hominem fallacy. This type of fallacy diverts the focus from the merits of the argument to the character, circumstances, or reputation of the individual presenting it.
For instance, if someone were to dismiss another's opinion on climate change by saying, 'You can't trust what he says about the environment; he's just a high school teacher,' they would be committing an Ad Hominem fallacy because they're not addressing the argument itself but instead, attacking the person's profession.
