Explanation by: Mr. Dubey

Bt seed refers to genetically modified seeds that contain a gene from the bacterium Bacillus thuringiensis (Bt). This gene produces a protein toxic to certain insects, particularly the bollworm, which is a major pest for cotton. Therefore, Bt cotton is widely used to protect the crop from pest attacks, reducing the need for chemical pesticides.

Why other options are incorrect:

  • (A) Rice – Although research is ongoing, Bt technology is not commonly used in commercially available rice.
  • (B) Wheat – Bt wheat is not commercially cultivated due to regulatory and market acceptance issues.
  • (C) Oil seeds – While genetic modifications exist for oilseeds (like Bt mustard is under trial), Bt cotton is the most prominent and widely accepted Bt crop.
