Consider a three sequentially stepped process named as Process A, Process B, and Process C. Input comes into Process A. Output from A goes into Process B. Output from B goes into Process C. Output of C is the final output. Suppose that it takes 2 minutes per unit in Process A, 3 minutes per unit in Process B and 1 minute per unit in Process C. Suppose further that Process A receives input at the rate of 30 per hour. Where would you place a buffer?
A) in front of Process A
B) in front of Process B
C) in front of Process C
D) in front of both Process B and Process C
E) None of these choices are correct.

Process B is the bottleneck since it has the longest processing time per unit (3 minutes), causing it to process at a slower rate than Process A. Placing a buffer in front of Process B helps to ensure it has a continuous supply of work and can help manage the flow between the faster Process A and the slower Process B.
