Answer:
Correct answer is British soldiers placed in Boston were provoked by colonists throwing stones and fired in the crowd, killing 5 Americans.
Step-by-step explanation:
Only the second option is correct, as none of other events are connected with Boston Massacre. To be more precise, none of this evidence happened, and are obviously invented.
Crispus Attucks, Samuel Gray, James Caldwell, Samuel Maverick and Patrick Carr were killed during this event, and therefore only second option as we have said is correct.
