less toxic to the pests that normally feed on them
B

C
unable to fix nitrogen in the atmosphere
D

Explanation: 

Detailed explanation-1: -In theory when a genetically modified plant is eaten, such genes can be transferred to bacteria in the gastro-intestinal tract of humans or animals. The bacteria could go on to develop resistance to that specific antibiotic.
