Unlike mitosis, meiosis results in the formation of
a. two genetically identical cells
b. four genetically different cells
c. four genetically identical cells
d. two genetically different cells

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
