Option C is correct since Campaigns can generate lead records in NetSuite without extra scripting or custom workflows. Pretty sure a lot of people get tripped up by B (Chat), but you'd need integration or SuiteScript to automate lead creation for that. If the question's about native, out-of-the-box capability, C is what they're after. Let me know if someone has actually seen B work automatically!
Seen this type of question on practice before. It's C here, as Campaigns can auto-create lead records natively in NetSuite. The others need extra setup or aren't automatic out of the box. Pretty sure that's what the exam wants, but ping me if anyone got something different.
Not B or D here. For native, automatic lead creation in NetSuite, I'm pretty sure it's C (Campaigns). Campaign sources can generate leads without manual intervention, while email/web chat usually need extra setup. Easy to get tripped up if you overthink customizations. Let me know if someone's seen otherwise!
