Answer:
C
Step-by-step explanation:
Ok so steamboats could cary like 30-50 tons, so b is incorrect.
steamboats are powered by steam... not by wind, so a is incorrect.
Go..o.g.l.....e says that there was a steamboat that had crossed the atlantic, so that automatically makes D false.
I would assume that steamboats increased trade and profits because goods could be moved more quickly.
