The correct answer is D. Collecting taxes
Step-by-step explanation:
Concurrent power refers to the power that is shared by different levels or entities in the government especially in the case of federal and state government which varies in each country and also changes over time. In the case of the U.S., an example of concurrent power nowadays is collecting taxes because both the federal and state governments or local governments have authority to establish and collect taxes which means power is shared equally. Also, others such as drafting soldiers or coning money are exclusive of the federal system. According to this, the one that is considered a concurrent power is collecting taxes.
