Observing Neutrinos from SN 1987A Was a Substantial Part of the Study

Observing neutrinos from SN 1987A was a substantial part of the study of the supernova. Which of these statements about these neutrinos is NOT true?

A) The neutrinos arrived at Earth before the visible light.
B) Neutrino detectors using Cherenkov radiation need not be pointed at their targets, so the neutrinos could be detected even though they were unexpected.
C) Only neutrino detectors in the southern hemisphere were able to record the event since the Large Magellanic Cloud is only visible in the southern hemisphere.
D) The discovery of neutrinos from SN 1987A provided strong support for the theory that supernovae are caused by the collapse of a star's core.
