So the answer is B, correct?

Yes, B -- the Olmecs.

To determine the correct answer to this question, we can break down the options and use a process of elimination.

A. Maya: The Maya civilization, located mainly in present-day Mexico and Central America, did build impressive stone pyramids. However, they were not the first Early American civilization to do so.

B. Olmec: The Olmec civilization, which existed in Mesoamerica from around 1500 BCE to 400 BCE, is credited with being the first Early American civilization to build stone pyramids. These pyramids served as ceremonial centers and were important structures in Olmec cities.

C. Aztec: The Aztec civilization, which rose to prominence in the 14th century CE, also built pyramids. However, they came much later than the Olmec civilization, so they are not the correct answer to the question.

D. Inca: The Inca civilization, which flourished in South America between the 13th and 16th centuries CE, is famous for its sophisticated stone construction, including Machu Picchu. However, they did not build stone pyramids.

Therefore, the correct answer is B. Olmec – they were the first Early American civilization to build stone pyramids.
