Which of the following is not an argument used against genetically modified food?
(a) it is new technology that unnaturally breaks genetic barriers between species
(b) it might cause allergic reactions.
(c) humans should not be designers of life.
(d) all of these arguments are used.

All of these arguments are used.

Explanation:

Genetically modified organisms or GMOs are the organism produced by the alteration or change in their genetic material. These organism are used for the production of recombinant proteins, antibiotics and food products.

The genetic barriers between two species are broken unnaturally. This genetic engineering is against the nature and humans creates the new design of life. The allergic reactions are also caused by these GMOs.

Thus, the correct answer is option (D).
