Solution

The correct option is B It can kill harmful bacteria
Bacillus thuringiensis, often abbreviated as Bt, is a naturally-occurring bacteria that kills pests when they eat it. The spores of these bacteria can be sprayed on crop plants. They give excellent control of leaf-eating caterpillars such as cabbage worms and tomato hornworms but has no activity against humans/animals when we consume them. Hence it can be used as an environment-friendly pesticide or insecticide.
