Which of the following accurately describes Louisiana's stance on 'gun-free zones'?

Louisiana does not have a blanket ban on all firearms in 'gun-free zones' as stated in option A. Option B is incorrect because the state does allow certain individuals, such as concealed permit holders, to carry firearms in these zones. Option C is also incorrect because Louisiana does recognize the existence of 'gun-free zones' and has laws pertaining to them. Option D accurately describes Louisiana's stance as it acknowledges that certain individuals, such as law enforcement and security personnel, may be exempt from the ban.
