To determine the production rate of the assembly line, we need to use the bottleneck time, which is the activity time of the workstation with the longest activity time. In this case, WS2 has the longest activity time of 30 minutes. Therefore, the maximum production rate of the assembly line would be:

60 minutes / (10 minutes + 30 minutes + 20 minutes) = 60 minutes / 60 minutes = 1 completed item per minute

So, in 60 minutes, the assembly line could assemble 1 item per minute x 60 minutes = 60 completed items. However, the question asks for the completed items every 60 minutes, so the answer is:

Answer: C) 12
