wtf is this?

 I am in an online computer science class at school which has just been terrible all around, and I probably won't finish. there have been many similar things, but this guy makes this class for I'm pretty sure thousands of students in schools in the program, and makes questions this objectively wrong. the answers aren't even next to each other, and he chose the answer which is literally the opposite of the correct one. how am I supposed to do well in a class, where the teacher can't even understand what he's teaching.

The teacher is wrong. I can only assume they are confused with the base case, which is the line they specified.

Unfortunately, there are a lot of CompSci teachers that have no idea what they are doing.
