A) collect and bring back soil samples from Mars
B) discover new planets like earth in the Milky Way

D) develop new tools for Mars exploration

not sure if this what   you'r looking for would be percent composition

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).
