Which would be the best choice to observe the movement of chromosomes during cell division?

Louis Pasteur investigated the problem of the disease Anthrax which attacked sheep. He was curious to know why it reoccurred in the same fields, sometimes at intervals of several years. (1) He noticed that in a field, patches of soil different in colour to the rest, where sheep which had died from Anthrax had been buried. (2) The idea came to Pasteur that worms travelling from the depths of the soil to the surface brought soil from around the carcass to the surface. (3) This soil could therefore contain Anthrax spores. (4) He dissected some of the worms from the patches of soil and fed some guinea-pigs with soil from inside the worms. (5) These guinea-pigs contracted Anthrax. Statement 2 is:
