I agree with B, even though the answer could also be wrong. Could have been a routing change and not a change on policy id 1 that dirtied the session.
But B is the most likely correct answer.
A dirty session is a session that must be re-evaluated by the kernel after it is impacted by a routing, firewall policy, or interface change. FortiGate performs route lookups for both original and reply traffic. Also, during route lookup, policy routes are also checked.
