Given the state of scientific knowledge at the time, which of the following would have been the most appropriate hypothesis for Semmelweiss to test?

If medical students wash their hands more carefully, then the rate of infection in their ward will go down.
If the medical students stop examining dead bodies, then the death rate in their ward will decrease.
If the medical students move their patients to the midwives' ward, then the death rate of their patients will decrease.
