There's no single 'true' answer, and it may depend on your implementation. You may not wish to put it in the Ready queue as it's not yet Ready to run, and you may not wish to keep it in the (a) Blocked queue if that would interfere with your implementation's finding which process is still waiting on I/O. Is your question one of understanding what's happening, or of how to implement it (which doesn't matter)?
