Northern Trail Outfitters want to allow its consumer to self-register on it business-to consumer (B2C)...

For Experience Cloud self-registration with Person Accounts, Salesforce requires the org and site configuration to line up with how external users are created. Person Accounts must first be enabled at the org level. On the site, the default account field must be left blank so the self-registration process doesn’t force users into a shared business account model. Public access settings also need access to the relevant Person Account and business account record types so the registration process can create the right record. This is the documented pattern when self-registration is meant to create people as customers rather than contacts under a standard account. The key idea is that registration must be allowed to create the correct account model from the start. This is why options B, C, D work together as the correct solution.
