Final answer:
The Supreme Court determined that the Second Amendment backs an individual's right to own a firearm for traditional legal purposes in the case of District of Columbia v. Heller. Option (b) is correct.
Step-by-step explanation:
The Second Amendment protection for an individual's right to possess a firearm unrelated to service in a militia was established in the United States Supreme Court case District of Columbia v. Heller. This landmark decision was made in 2008 when the court ruled in 5-4 decision that the Second Amendment protects an individual's right to possess a firearm for traditionally lawful purposes such as self-defense within the home. This case distinguished from previous interpretations which have tied the right to bear arms to militia service.
