Answer:
B.China’s economy expanded as farmers using iron tools were able to grow more food.
Step-by-step explanation:
The Zhōu dynasty was a Chinese dynasty that governed between around 1122 a. C. and 249 a. C. It is the third Chinese dynasty in traditional history, and the second, after the Shang dynasty, of which there is evidence by written sources of his time. The arts and ornamental techniques flourished, which manifested, as in many Mesoamerican and European cultures, the desire of men to communicate with the immortals. The Zhōu dynasty was the last of the dynasties of kings before the imperial dynasties. In this time the great Chinese thinkers of antiquity lived, like Confucius, and classical Chinese literature began.
