Answer:
B. public elementary schools in almost every town in the state.
Step-by-step explanation:
It was documented that in the early 19th century, the New York State had established a system of public schools that are located across the state, by the common school law of 1812. This system was controlled under the leadership of Gideon Hawley who serves as the first Superintendent of Common Schools.
Hence, by the 1820s, the state of New York's education system had established "public elementary schools in almost every town in the state."
