Which individual is known as the NYC Mayor?

The correct choice is Eric Adams, who serves as the Mayor of New York City. As the Mayor, he is the chief executive officer of the city, responsible for overseeing the city's administration and implementing policies that affect the city's residents. His role includes managing the budget, directing city services, and representing the city in various capacities.

In contrast, Kathy Hochul is the Governor of New York State, not the mayor of the city. Edward A. Caban is the Police Commissioner, overseeing the NYPD, and Mark T. Stewart does not hold a prominent political office related to the city's governance. This delineation of roles clarifies why Eric Adams is identified specifically as the NYC Mayor.
