The correct options are
A The failure to repay loans
D Crop failure and subsequent losses
The movement of people from rural areas or villages to urban areas or cities is called rural-urban migration. Often times, it is the smaller farmers who find themselves in situations that force them to migrate to urban areas. Crop failure and the inability to repay loans are two such factors that have caused small farmers to move to urban areas in search of non-agricultural jobs and a steady income.
