The purpose of the Terracotta soldiers was to guard the tomb of the emperor shihuangdi (option "D" is the correct one). The Terracotta Army was built to accompany Qin Shi's tomb who was the First Emperor of China. This collection of Terracotta sculptures, also known as the "Terracotta Warriors and Horses", was buried with the emperor between 210 and 209 BC intended to guard him in his afterlife. The Terracotta sculptures has been considered one of the most important archaeological discoveries of the 20th century.
