The correct answer is B. Under the standard CGL condition titled Duties in the Event of Occurrence, Offense, Claim or Suit, the insured must see that the insurer is notified as soon as practicable of an occurrence or offense that may result in a claim. The notice should, to the extent possible, identify how, when, and where the occurrence happened, the names and addresses of injured persons and witnesses, and the nature and location of resulting injury or damage. New York Court of Appeals decisions reproduce this CGL condition substantially verbatim.
Option A is incorrect because the standard CGL does not establish a universal seven-day reporting deadline. Option C is defective because cooperation is not discretionary; the insured must cooperate with investigation, settlement, and defense and provide assistance when requested. Option D is far too broad because the policy does not require reporting every business matter.
Once an actual claim or suit is received, additional duties apply, including promptly notifying the insurer and forwarding demands, notices, summonses, and legal papers.
The Series 17-70 outline specifically covers CGL conditions, occurrence versus claims-made coverage, investigation, and duties after loss or claim.
