Based on the information in the table, the sum of the task times for each station is 9.6 minutes for station 1, 6 minutes for station 2, and 12 minutes for station 3. To calculate the cycle time, we add those three times together (9.6 + 6 + 12 = 27.6 minutes) and divide by the desired output rate (90 units per hour, or 1.5 units per minute): 27.6 ÷ 1.5 = 18.4 minutes. Since each station must take less time than the cycle time, we can see that it is possible to have three stations, but not two. Therefore, the fewest number of workstations needed is three (choice B).
