Genetic engineering is the manipulation of genes using cloning and transformation to change the gene structure. genetic engineering has many positive outcomes. these positive outcomes include a) manipulation of crops decreasing growth rate. b) increasing the possibility of new pathogens . c) decreasing the diversity of living organisms. d) fruits and vegetables that do not spoil easily.

I would say the correct answer is D. fruits and vegetables that do not spoil easily.
To me, this seems like the only advantage to genetic engineering among these examples. A is incorrect because you would want your crops to grow faster, not more slowly; B is incorrect because pathogens are bad and you don't want them; C is incorrect because diversity is important. Thus, D is the only correct answer here.
