b. plant cells have more lysosomes than animal cells have.
c. plant cells have large vacuoles, and animal cells do not.
d. the position of the nucleus in the cells is different in plants and animals.

the answer is a) cell division.

hope this !

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).
