Can someone help me understand the answer?

Why does the question talk about f:A->B if in the answer B is never even mentioned?

This answer is so alien to the actual material the book presents i dont even know how to interpret it.

What is g:f(s) -> S? is f(s) B or the range of B?

It only ever talks about f:A->B and g:B->A or g:B->C including in other questions. I've never seen g:f(s)->S before.

Why do they have to introduce new material as answers to the questions? Sometimes this stuff is so demotivating.
