(D) It is an affirmative defense to a charge under division (A)(1) of this section of carrying or having control of a weapon other than a handgun and other than a dangerous ordnance that the actor was not otherwise prohibited by law from having the weapon and that any of the following applies:
(1) The weapon was carried or kept ready at hand by the actor for defensive purposes while the actor was engaged in or was going to or from the actor’s lawful business or occupation, which business or occupation was of a character or was necessarily carried on in a manner or at a time or place as to render the actor particularly susceptible to criminal attack, such as would justify a prudent person in going armed.
(2) The weapon was carried or kept ready at hand by the actor for defensive purposes while the actor was engaged in a lawful activity and had reasonable cause to fear a criminal attack upon the actor, a member of the actor’s family, or the actor’s home, such as would justify a prudent person in going armed.
(3) The weapon was carried or kept ready at hand by the actor for any lawful purpose and while in the actor’s own home.
