three key routing principles governing how SD-WAN rules process traffic are:

Policy routes take precedence over SD-WAN rules: Regular policy routes are evaluated before SD-WAN rules. If a policy route matches the traffic, the SD-WAN rules are skipped entirely.

Rules are skipped if the best route is not an SD-WAN member: By default, if FortiGate performs a traditional routing table lookup and the absolute best route (lowest administrative distance/metric) to the destination points to a non-SD-WAN interface, the custom SD-WAN rules are ignored, and conventional routing takes over.

Members are skipped if they lack a valid route to the destination: An SD-WAN member interface specified within a rule will be bypassed entirely if it does not possess a valid route entry in the routing table leading to that specific destination.

A is incorrect as Directly connect routes do not have precedence over SDWAN rules

ADE is correct. B is also corect as it is written and it seems this option is worded wrongly, as ISDB routes also takes precedence over SD-WAN rules.

ISDB are treating like Policy Route so it has precedence over SD-WAN
directly connected is part of RIB and Routing table doesnt have any precedence over SD-WAN

Fortigate 7.6 Administrator Study Guide, page 90. The diagram about the Route Lookup Process is clearly explain there.
