The correct option is C: Slippery slope. This type of fallacy suggests that a certain or certain events will take place with no real or sufficient evidence to prove so. This is the case, especially with events that seem unlikely to happen given the circumstances. In this example, the reasoning goes like this: if Quentin fails to pass his math test, as a consequence, he will lose the opportunity of going to college and he will have to live in his parent’s basement for the rest of his life. However, the fact that he does not pass this test is not enough evidence that those two situations will actually take place. For example, Quentin may take the test again and try passing it, or if he eventually cannot enter college, he can look for a job that is profitable and that will allow him to become independent and move from his parent’s house, etc.
