Where is snap_size from? Where is LinearMark from? You don't need to
instantiate LinearMark in B, do it in A.

What error do you get when you instantiate LinearMark in A? Please

If LinearMark is imported in from C, you can do:
from C import LinearMark
from B import LinearMark

lmark = LinearMark(name)

Or do you want to use class method of LinearMark?

Since you don't provide any code, it's really hard to tell what you're
