In a plants stem the vascular tissue is a. is always arranged in rings of vascular bundles b. is continuous from the roots to thel leaves c. carriers nutrients up the stem but not down d. plays a role in photosynthesis and storage.

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).
