Step-by-step explanation:
The correct answer is b. State income tax for a member of the military is based on where wages are earned.
While members of the military are employed by the federal government, they are still subject to state income tax based on where their wages are earned. This means that if a member of the military earns income in a particular state, they may be required to pay state income tax to that state.
