second approach is best forgiven system. 

In my opinion, approach 'b' will best suit this system because as the deadlocks are less likely to happen and processes are frequently requesting resources, running the algorithm after specified period of time will not slow down the system much but if the first approach is used that after every request the algorithm is run, and as the requests are quite frequent, it will slow down the system a log and processes will experience lag. 
Hence its best to run the detection algorithm after a specified time for deadlock detection.
