What right is implied by the Second Amendment's right to bear arms?

a. the right to own property

b. the right to defend one's honor

c. the right to form a private militia

d. the right to protect yourself

(c) the 2nd amendment gives the right to form own militias, protecting oneself from possible tyranny of the president (control over the army)

The correct answer actually is D.

Second amendment states:

A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.

This, even though it can seem like it, does not mean private militia. It means militia in a sense of what it meant during the War of Independence. It was the colonist militia that fought against the British. Thus this refers to a right to defend oneself against an oppressive government and outside forces.
