What is the definition of a concealed firearm?

A concealed firearm is defined as a firearm that has any part of it hidden from view, so option B accurately captures this definition. The essence of concealed carry is that the firearm is not visible to others, which allows the carrier to conceal their weapon from the public eye. This can involve the firearm being tucked away in a holster under clothing or otherwise obscured.

In contrast, a firearm that is in plain sight does not fit the definition of "concealed," as visibility undermines the concept of concealment. Firearms issued by law enforcement are generally considered service weapons and are not defined by concealment. Additionally, while firearms are often carried for self-defense, this purpose does not inherently categorize them as concealed; the critical factor remains whether they are hidden from view.
