which is an implied power of the federal government? raising taxes regulating trade drafting soldiers declaring war

The implied power of the federal government from that list is drafting soldiers.

Why “drafting soldiers” is implied

• Raising taxes , regulating trade , and declaring war are all powers that are explicitly listed in the Constitution as powers of Congress, so they are expressed powers, not implied ones.

• The Constitution gives Congress the expressed power to raise and support armies, and from that power, the government has developed the implied power to create and enforce a military draft, even though the word “draft” never appears in the Constitution.

So, among the options given, drafting soldiers is the implied power.
