Mass and Balance Questions - Traffic Load

I wonder if there are any brain boxes out there who can shed some light on this question? I have (as far as I am aware) followed the correct proceedure of how to calculate a Traffic Load.

MTOM: 170 000kg
ZFM: 112 500kg
MLM: 148 500kg
DOM: 80 400kg
TAXI FUEL: 800KG
BLOCK FUEL: 40 000KG
TRIP FUEL: 29 000KG.

Question asks for the traffic load which can be carried.
Here are the choices:
A) 32 100kg
B) 32 900kg
C) 18 900kg
D) 40 400kg

My calculations:

(*1) (I have calculated MTOM fuel to be block fuel (40 000kg) - taxi fuel (800kg) = (32 000kg) )

(*2) (I have calculated MLM fuel to be block fuel (40 000kg) - taxi fuel (800kg) - trip fuel (29 000kg) = 10 200kg

MTOM / ZFM / MLM
LIMIT 170 000kg / 112 500kg / 148 500kg
DOM 80 400kg / 80 400kg / 80 400kg
FUEL 39 200kg (*1) / ------- / 10 200kg (*2)

=TRAFFIC LOAD 50 400kg / 31 600kg / 59 900kg

THE CORRECT ANSWER SHOULD BE A but I don't get anywher near that!

Can anyone tell me where i have gone wrong? I thought that I had these mass and balance questions sorted

I'm currently studying with Bristol, but the question was taken from 'The Daily ATPL' website.

I would be so grateful if anyone could help me
