The correct answer is: A. 2000 BC.
King Hammurabi was the sixth king of the First Babylonian Dynasty. He is best known for his Code of Hammurabi, a well-preserved Babylonian code of law of ancient Mesopotamia, dated back to about 1754 BC. The Code consists of 282 laws, with scaled punishments, adjusting “an eye for an eye, a tooth for a tooth” (lex talionis) as graded depending on social status, of slave versus free man.
Hammurabi’s army was one of the most powerful in the world at the time. It was made up of professional soldiers who were well-trained and equipped. The army was used to conquer new territory and to defend Babylonia from its enemies.
The other options are incorrect because they are not the dates when King Hammurabi raised the first army of the world.
