Answer:
B. Political machines controlled economic activity in New York.
Step-by-step explanation:
In the political cartoon, the statement that is the most accurate is "political machines controlled economic activity in New York."
In U.S politics, political machines are known to be an organization of a party which is usually headed by a single boss who usually command votes to maintain and control a city, state or country.
In New York, when political machines are appointed, they control government salaries and revenues to sponsor parties.
From this political cartoon, it's clearly seen that William Tweed is the man represented with the big thumb. This shows his control over New York.
William Tweed had control over political patronage in New York through Tammany. He was known as the "boss" of Tammany Hall. He was known to be the third-largest landowner in New York City. He played a major role in the 19th-century politics of New York City.
