Petroleum-lysing bacteria are being engineered for the removal of oil spills. What is the most realistic danger of these bacteria to the environment?

What could be the possible harm of using an antibiotic-resistant gene as a selectable marker in a plasmid,used for gene transfer in the production of $GM$ food?
$(A)$ $GM$ food contains the enzyme produced by the antibiotic resistance gene that was used during gene transfer in genetic engineering. This could cause allergies since it is a foreign protein.
$(B)$ The bacteria present in the alimentary canal of humans could take up the antibiotic resistance gene present in $GM$ food.
$(C)$ The bacteria in the human alimentary canal would then become resistant to the concerned antibiotic.
$(D)$ The transgene may be transferred through pollen to their wild relatives and make weeds more persistent and damaging.

While creating genetically modified organisms,genetic barriers are not respected. How can this be dangerous in the long run?

According to $NCERT$ text, which Indian plants have either been patented or attempts have been made to patent them by Western nations for their commercial use?
$I$. Basmati rice $II$. Neem
$III$. Turmeric $IV$. Tulsi

Give any two reasons why the patent on Basmati should not have gone to an American Company.

The use of bioresources by multinational companies and other organizations without proper authorization from the countries and people concerned without compensatory payment is called:
