12)In effect of busy-waiting on performance. Placing a data item into the buffer takes 10 ms when executed in isolation. Similarly, the removal of a data item takes 10 ms. (Assume that the quantum Q is much smaller than the time to execute the CS.) When the producer and the consumer run concurrently on one CPU and the producer begins filling the buffer at time t, the consumer will finish emptying the buffer at time. a) t+10 b) t+ 20 c) t+40
