I think Bounce address tag validation is the way to go.

From what I recall, FortiGuard IP Reputation helps block known bad IPs, which might help reduce unwanted DSNs, but I’m not certain if it’s the best answer for this scenario.

I practiced a similar question where we had to identify techniques to handle spoofing. I feel like spoofed header detection could be relevant, but I’m not entirely confident.

I think bounce address tag validation might be the right choice here since it deals with validating the return addresses of emails, but I could be mixing it up with another concept.

I remember studying about DSNs and how they can indicate issues with email delivery, but I'm not sure which antispam technique specifically addresses this.

I'm a little unsure about this one. The options all seem relevant to preventing spam, but I'm not totally clear on how each one would specifically address the DSN issue described in the question. I might need to review the FortiMail documentation to feel more confident in my answer.

Spoofed header detection, huh? That makes sense. I was also considering FortiGuard IP Reputation, but that's more for blocking known bad senders, not necessarily preventing spoofed DSNs. I'll go with Spoofed header detection on this one.

Okay, let's see. The question is asking about preventing a sudden increase in DSNs, and it says the DSNs were not generated by any outbound email from the organization. I'm thinking Spoofed header detection might be the way to go here.
