幸亏 means something like luckily, thanks to the fact that, or it’s a good thing that. It often expresses relief: a bad result was possible, but it did not happen because of some fortunate condition.
So in this sentence, 幸亏她能听清楚伴奏 means:
- Luckily she could hear the accompaniment clearly
- or It’s a good thing she could hear the accompaniment clearly
This is different from 因为, which just means because and is neutral. 幸亏 adds the speaker’s feeling that the situation could have gone badly.
能 here means to be able to, especially because of actual ability or circumstances.
So 她能听清楚伴奏 means:
- she is able to hear the accompaniment clearly
Why not the others?
- 能: ability or possibility under the circumstances
- 会: can mean know how to or sometimes future/likely outcome
- 可以: permission or possibility, more like may/can
In this sentence, the point is that she had the ability/opportunity to hear it clearly, so 能 fits best.
