The Cry-l gene, produced by the bacterium, is responsible for insecticidal activity. Which bacterium produces it?

Correct option is C

The Cry-l gene is derived from the bacterium Bacillus thuringiensis (Bt).
The Cry proteins are insecticidal and specifically target insect larvae by binding to their gut receptors.
Bt genes are widely used in genetically modified crops, such as Bt cotton and Bt brinjal, to provide resistance against insect pests.
This has significantly reduced the use of chemical pesticides in agriculture.
