For the light stage of photosynthesis to occur, sunlight must be present. At this time, water is split to produce which of the following?

Explanation:

Water is split into oxygen (O2), protons (which are then used to form ATP), and electrons (which travel down the electron transport chain)

we would need to see the picture to answer it

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).
