The correct option is D All of the above
Transgenic plants produce their own built-in pesticide, in every cell, which kills the pest and insects. These safe claimed pesticide are produced in more concentrated form than natural Bt spray and hence, become more toxic. As an allergen, these toxins cause significant immune disregulation and lead to allergic diseases like asthma and inflammation. This is because our body recognize the enzyme produced by the antibiotic resistance gene as a foreign protein. The human alimentary canal bacteria can take up the antibiotic resistance gene from GM food and can become resistant to the concerned antibiotic, making it difficult to manage them.
