It’s either A or B but I say because I found the story I think B
A: The first one is inherent powers. The Post Office is mentioned in Article 1 Section 8 and is the 7th clause down right in the constitution. It is a right given to the Federal Government to set up Post Offices.
B: The second one also comes from Article 1 Section 8. It is called the Elastic Clause and it allows the Federal Government to to add laws so it can carry out its duties. It is the last clause of Article 1 section 8. Things like highways and borders come under this clause. The answer is 4. Implied Powers.
C: Actually C is granted by the Constitution. Defense must be given to some governing body. This too is Article 1 Section 8. It is in the very first clause. Since it is in the constitution, the right is inherent. Two answers that are the same makes me very nervous, but when something is in the constitution there is no choice but to pick it as an inherent right.
D: Both state and federal governments can tax. These are concurrent powers.
E: The constitution prohibits any law that would show bias or support to an established religion. It is a denied power. This is straight out of Amendment 1.
The answer is: Postconventional
A postconventional level of moral development happens when an individual has the capability to form their own ethical standard even though those ethical standards MAY NOT be accepted by the society. For example, a Man who fight for Women's equality in middle east.
