The correct answer is A) high relief, and B) low relief.

Sculptures that decorated buildings came in two styles. High relief ones were carvings that had more of a three-dimensional effect, while low relief sculptures were very close to the original wall.

Relief is the element in sculptures that is in the surface of the sculpture. Like the ones we find in churches or Greek buildings, like the Parthenon or in Mexican temples. Low relief sculptures are the ones that standout from the back of the sculpture. They are almost done in the surface. High relief ones are carved more deeply and you can note the difference and the contrast in the relief.
