D. 12 supervisors

Explanation:
If there are 2 hall monitors per hallway, then there are a total of 2 x 30 = 60 hall monitors in the school.
If there are 4 supervisors for every 20 hall monitors, then there are 60/20 = 3 sets of 20 hall monitors requiring 4 supervisors each.
Therefore, Mr. Smith will need to appoint 3 x 4 = 12 supervisors.
