In the dryer vent scenario, to determine which insurer is responsible for the claim, Mark must decide which timing rule applies. Which option correctly describes this rule?

• A. When the damage occurred
• B. When the damage was detected
• C. When Mark renewed his policy
• D. The date of the neighbor's notice

Answer: (B)

The timing rule being tested is the discovery rule: the insurer that should respond is the one active when the damage is actually discovered by the insured, not necessarily when the damage occurred. In a dryer-vent scenario, problems can develop quietly over time and aren’t noticed right away. When Mark first detects the damage, that moment determines which policy is on the risk for handling the claim. This aligns coverage with the point at which the insured becomes aware of the loss and can report it.

If the rule were based on when the damage occurred, the claim might be assigned to a different policy than the one in force when the loss was found, which isn’t consistent with how discovery-based triggers work. Renewal dates and a neighbor’s notice don’t determine which insurer is responsible for the claim.
