E (chosen and correct)

How much time would be required for a setup, using your suggestion in (b)?

Explanation / Answer

Limiting the number of trips to tool room to one will decrease the time taken by 40 minutes because "Return to lathe" and "Return to Tool Room" takes 20 minutes each.
Changing the location of fixture can reduce some time as removing fixture and installing new fixture is taking about 20 minutes.
eliminating the tool room and instead locate the tools in a visible location near the lathe. This will reduce reduce some time of going to the tools room and returning to lathe.
change the entire lathe room layout, so that fewer steps are required to turn the lathe on and off, as well as clean the lathe and change fixtures for the lathe : this will reduce some time from all the elements of the task which cumulatively will reduce time taken for the setup effectively.
