The correct answer is C. The Hudson River School specialized in landscape paintings.

Explanation:

Hudson River School was a group of 19th-century American landscape painters who painted in the Hudson River area of New York State. It was the first national American painting school, created in the 1830s under the direction of Thomas Cole. The motifs were romantic landscapes taken from the Hudson River and The White Mountains of New Hampshire, the Catskill Mountains, the Adirondack with wide views and rich detail, inspired especially by German romantic painting. Painters considered for the school include Thomas Doughty and Asher Brown Durand. The movement lasted until the end of the 19th century with, among others, Frederic Edwin Church as the representative of a later generation.
