Answer:
E. Permitted blacks to work in the occupation of their choice.
Step-by-step explanation:
Black codes, according to Douglas Blackmon, is described as 'slavery with another name', because black people was restricted in so many ways, despite their 'freedom' after civil war.
Vagrancy Law was the defining feature. This law allowed local authorities to arrest freedpeople for whatever minor infraction to commit them to involuntary jobs, this is why Blackmon called it SLAVERY WITH ANOTHER NAME.
So, Black Codes and commercial laws excluded blacks from certain trades and businesses, also their ownership were restricted too. That's why blacks were not permitted to work in the occupation of their choice. There wasn't freedom actually.
