Answer:
"The colonists were making their own goods instead of buying from the British."
Explanation:
The piece of evidence that supports that British merchants lost money because the Sons and Daughters of Liberty boycotted British goods is that "The colonists were making their goods instead of buying from the British."
This was evident in the fact that the Daughters of the Liberty went against the Stamp Act by refusing to take British goods such as British Tea and clothing materials.
Instead, they made their teas through local herbs and berries, while they also made homespun cloth instead of buying from British merchants.
