Chemistry (Kinetics, 0th, 1st, 2nd order) question

There are 4 results of experiments: The first one consists of: 2 A-molecules, 2 B-molecules & 2 C-molecules. The second has: 2A, 2B & 4C. The third has 1A, 2B & 2C. The fourth has 2A, 6B & 1C.

The reaction rate/speeds (not sure what it's called in english) are:
experiment 1: experiment 2: experiment 3: experiment 4
2 : 4 : 2 : 3

Which order reaction rate are A, B & C?

I'm sure that A is zeroth order, because when you look at experiment 1 & 3, the concentration A-molecules halves, yet the rate doesn't.

C must be first order, because when you compare experiment 1 & 2, the concentration of C-molecules doubles & the reaction rate doubles as well.

Now B is the only one I don't know, I just can't figure it out. Help would be appreciated!
