During world war i, which weapon was most likely to cause unintended deaths?

It depends.  It could be from artillery or from gas.  There are instances where coordinates were miscalculated and that resulted in the bombardment of their own soldiers.  Gas can be another weapon because once it is unleashed anyone can be affected if they don’t wear their gas mask.

i think the answer would happen to be the letter b

the option which was not a function of missionaries in the northwest was the first one - they established posts for trading furs and other goods.

missionaries were sent around the world to spread religion and their knowledge and others - they were not merchants who sold furs and other goods.
