The correct answer is B - 21 years. In Washington DC, the minimum age to register a firearm is 21 years old. It is important for individuals to be aware of and adhere to this legal requirement to ensure compliance with DC gun laws and promote responsible firearm ownership.

Option A, 18 years, is not correct as the minimum age to register a firearm in DC is 21 years old, not 18 years. Option C, 25 years, and Option D, 28 years, are also not correct as they do not align with the actual minimum age requirement set by the laws in Washington DC.
