The correct answer to why convict-leasing was eventually outlawed in Texas is:
D. Too many convicts died in the state after being forced into unpaid labor.
Convict-leasing involved prisoners being leased out to private individuals or companies for labor without pay. The practice often resulted in harsh and dangerous working conditions that led to many convicts losing their lives. Due to the high mortality rates and the inhumane treatment of prisoners in this system, there was growing public outcry and pressure to abolish convict-leasing in Texas and other states. This eventually led to the outlawing of the practice to protect the well-being and rights of prisoners.
