Which of the following is NOT a benefit of plant biotechnology

a. moving herbicide resistance to weeds

b. increasing the strength of cotton fibers

c. producing plants that are resistant to herbicides

d. introducing vaccines to specific types of plants

a. moving herbicide resistance to weeds

Explanation:

Herbicides are chemicals that are used to kill unwanted plants that can affect the growth of crops. Herbicide resistant plants are those that do not die following exposure to a herbicide.

Moving herbicide resistance to weeds would mean that weeds do not die following herbicide treatment, which is not a desired effect of biotechnology. Therefore, a is correct.
