I’m pretty sure the answer is the first option, but I could be wrong
Yes it’s true............
I believe imperialism because it means gaining on one country's power
On 18 June, the United States declared war on Great Britain, citing, in part, impressment. After the Napoleonic Wars impressment was ended in practice, though not officially abandoned as a policy. The last law was passed in 1835, in which the power to impress was reaffirmed.
C- colonization era
Constitution era obviously isnt it
Reform era was known as the progressive era
the early republic era had to with transfer of govt
thus leaving colonization era as the last option
