Explanation:

phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

genotype is the genetic constitution of an individual organism.

Hope this helps

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).
