What does "reefing" a sail mean, and roughly when might a skipper decide to do it?

A. Reefing means removing a sail completely and stowing it below decks
B. Reefing only applies to the mainsail, never to a headsail
C. Reefing reduces the effective area of a sail that's exposed to the wind, typically done as wind strength increases, to keep the boat manageable, reduce heel, and reduce strain on the rig and crew — a sensible skipper reefs earlier rather than later, since it's far easier and safer to reef in moderate conditions than to wait until it's genuinely blowing hard
D. Reefing is a manoeuvre used exclusively when returning to harbour
