The correct options are
A Low harvest
B Deterioration of soil quality
C Depletion of groundwater resources
D Vulnerability over farmer's household food security
In contract farming, the farmers agree to cultivate certain crops after recieving financial aid from the companies. Due to the extensive use of chemical fertilizers, the soil quality deteriorates and groundwater level depletes. Thus, the yield declines over time. Often, farmers use their best lands for contract farming, jeopardizing their own household food securiy.
