Answer:
2 and (probably) 4
Step-by-step explanation:
Christopher Columbus was of Italian Heritage, but sailed to the New World for Spain because Queen Isabella I of Spain agreed to fund his voyage.
Option number 4 is worded a little weird (that's why I'm unsure if it's a correct answer), but Columbus sailed west with the intention of finding a faster route to India, so when he first arrived in the New World, he assumed he was India.
