Le /8 means that you are allowing /8 /7 /6 /5 /4 /3 /2 /1 within the
128.0.0.0 - 255.255.255.255 IP range.
Supernets of a class B? Wouldn't that mean multiple class B's? So you
should look for "le 15" as your answer.

Not quite sure if I understand the question.
Is it asking to allow all prefixes which start with 128 but are less than or
equal to /8? In other words supernets of class-B 128 with le /8....
If this is the case I would go with 128.0.0.0/1 le 8
Victor,
I believe the statement 0.0.0.0/1 ge 2 le 8 will match all class-A networks
but will not match 128.0.0.0/8.
