Which statement best describes the doctrine of dual sovereignty? a. a person cannot be tried for the same crime twice b. a person cannot be tried for two crimes in one trial c. each government has the right to punish those who violate its laws d. each court is a sovereign entity with its own sphere of jurisdiction

The doctrine of dual sovereignty states that a person may be prosecuted by two different states if the criminal act breaks the law of each sovereign state. So, the answer to this question will be C.  Each government has the right to punish those who violate its laws. As each government is sovereign and has its own sphere of jurisdiction an individual may be prosecuted for the same crime by different states.

this isn't a question and if you're going to list things be kind and use commas.
