A company that repairs and maintains HVAC systems for businesses wants to assign three service teams to three geographical zones, one team to each zone.
 
  Because of the familiarity with each team to the companies located in a zone, there are differences in the efficiencies of each team, reflected in the service costs. The matrix below shows the service costs (in thousands of dollars) for each team in each zone. Assign each team to a zone that minimizes cost.
  A) Assign T1 to zone A, T2 to zone B, and T3 to zone C.
  B) Assign T1 to zone A, T2 to zone C, and T3 to zone B.
  C) Assign T1 to zone B, T2 to zone A, and T3 to zone C.
  D) Assign T1 to zone B, T2 to zone C, and T3 to zone A.
  E) Assign T1 to zone C, T2 to zone A, and T3 to zone B.
