Answer:
Step-by-step explanation:
The main reason the Panic of 1837 led to an economic depression in the United States was B. The United States' lack of a central bank.
The Panic of 1837 was a financial crisis that began in the United States in 1837 and lasted until 1843. The crisis was caused by a number of factors, but the primary cause was the lack of a central bank in the United States. At the time, the country was on a decentralized banking system, which made it difficult for banks to respond to financial crises, and caused a series of bank failures and a severe contraction of credit. The crisis also highlighted the vulnerability of the nation's monetary system, which was based on the gold and silver standard.
The other factors you listed - the sudden repeal of the Tariff of 1828, a drop in land prices after Cherokee migration and Conflicts during the nullification crisis - may have contributed to the economic downturn, but the lack of a central bank was the main cause.
