If pharmaceutical researchers want to learn how to keep cancer cells from dividing uncontrollably, which approach are they most likely to try?

Interrupt some stage of the cell cycle, such as the formation of the spindle that separates chromatids.

Develop strong dyes that will be able to color the chromosomes for good visualization.

Provide dangerous levels of radiation to irradiate the
cancer cells in a human being.

Starve the cancer cells by starving the patients, thereby reducing chances of cell division.
