Answer:
b. a dogu
Step-by-step explanation:
The Dogu sculptures, (discovered by AP Kazantzev in the Tohoku Region, on Honshu Island, Japan) were made by a Japanese Neolithic people called JOMON, 7,000 years ago, being the first people on earth, who handled the clay and turned it into ceramics.
According to Carbon-14 data, we must go back from 12,000 to 14,000 years, to place ourselves at the time from which the first Dogu sculpture comes.
Dogu sculptures are truly unique. There are no other figures like them in the ancient world, they do not resemble any other object appeared on earth.
