What type of art is characterized by huge sculptures of heads and intricately carved stone works?

The correct choice is Olmec Art, which is well-known for its distinctive large stone sculptures, particularly the colossal heads that are a hallmark of this ancient Mesoamerican civilization. These sculptures, often weighing several tons, were carved from basalt and depict human heads, believed to represent rulers or important figures. The intricacy of their features and the sheer scale highlight Olmec artistic skill and cultural significance.

In contrast, Assyrian Art is primarily known for its relief sculptures and palace decorations, which often feature historical events and gods rather than large heads. Medieval Art encompasses a wide range of styles during the Middle Ages, including illuminated manuscripts and Gothic architecture, focusing more on religious themes than monumental stone carvings. Romanticism, an artistic movement in the late 18th to mid-19th centuries, is characterized by expressions of emotion and nature, rather than the monumental and sculptural focus seen in Olmec Art.
