Answer: A

Explanation:

A is correct.

A simulator is not a real device and doesn’t have the hardware and connectivity characteristics that the real device has.

B is not correct because you can thoroughly test a simulator, but that still won’t get around the problem in A.

C is not correct because this is precisely why simulators are used C they are easily cloned.

D is not correct because simulators can certainly run concurrent applications
