A corporation has been the subject of several news reports charging that the pollution put out by its factory endangers 5,000 residents of a subdivision. The corporation filed an action naming all 5,000 residents as defendants and seeking a declaratory judgment that it is not liable for damaging their health, and the court properly certified the action as a class action. Per court order, detailed notice of the suit is posted on every lightpole throughout the subdivision, but the residents are not notified individually. Was notice in this case constitutional?
A. Yes, because the posting was reasonably calculated to give notice to all 5,000 residents.
B. Yes, if a state statute authorizes such process.
C. No, because all residents could reasonably be notified by mail.
D. No, because individual defendants must always be notified by personal service of a summons.
