Aeronautical researchers have developed three different processes to pack a parachute. They want to compare the different processes in terms of time to deploy and reliability. There are 1,200 objects that they can drop with a parachute from a plane. Using a table of random digits, the researchers will randomly place the 1,200 items into three equally sized treatment groups suitable for comparison. How should the items be labeled to select the process groups using a table of random digits?

A. 1–3

B. 1–1200

C. 0000–1200

D. 0000–1199
