Which feature of PAN-OS SD-WAN allows you to configure a bandwidth-intensive application to go directly to the internet through the branch's ISP link instead of going back to the data-center hub through the VPN tunnel, thus saving WAN bandwidth costs?
The feature of PAN-OS SD-WAN that allows you to configure a bandwidth-intensive application to go directly to the internet through the branch's ISP link, instead of going back to the data-center hub through the VPN tunnel, is SD-WAN direct internet access (DIA) links. This approach saves WAN bandwidth costs by enabling direct access to the internet from the branch.

I think B, from doc below: You may have cloud-based services and instead of having your internet traffic flow from branches to the hub to the cloud, you want the internet traffic to flow directly from branches to the cloud using a directly connected ISP. Such access from a branch to the internet is Direct Internet Access (DIA)
It's called a SPLIT TUNNEL. but of course palo alto just like all the vendors always have a mind battle where they love to re-name existing terminology because of their own ego. but yes answer is C
Correct your answer admin. It can not be "D"
B.- SD-WAN direct internet access (DIA) links
In a split tunneling scenario, you want only a particular bandwidth-intensive application to go directly to the internet through the branch’s DIA link instead of going back to the data center hub through the VPN tunnel, thus saving WAN bandwidth costs. Link provided by TAKUM1y & nose999
