Option A
I get why B looks tempting since those headers seem unique, but they're easy to spoof. A is safer here.
Option A makes sense here since only cryptographically verifying the JWT assertion really proves traffic is from IAP. Headers like in B or D are too easy to spoof. Pretty sure it's A, unless I'm missing something subtle.
A tbh
C is not right, A is what you want here. Official guide covers this IAP JWT validation topic in the security chapter.
