What type of background check is mandatory for firearm registration in Hawaii?

In Hawaii, both national and state-level background checks are mandatory for firearm registration. This strict requirement ensures that individuals looking to register firearms are thoroughly screened at both levels for any disqualifying factors that would prevent them from legally owning a firearm. This dual background check process helps maintain the safety and security of the community by preventing those with criminal backgrounds or other disqualifying factors from obtaining firearms. While the National Instant Criminal Background Check System (NICS) may be part of the process, Hawaii law also requires additional state-level checks to be conducted, making option C the correct answer.
