Maybe it's better to say: Black to free the 2 stones in the corner. That is because white can escape after that. But that will most probably be a success for black.

I would try b5, but without any conviction :)

Bb5, Wb3 and white has 2 eyes. One at c1 and the other at the stones in the corner.
But you're close :-)

I can't believe it's Ba5... so unnatural :)

Bb5 is not correct. After Wa4, black has no answer.
