Which of the Following Best Describes the First Set of Experiments

Which of the following best describes the first set of experiments, using chlorine traps, that were searching for electron neutrinos from the Sun?

A) All the experiments had technical problems detecting neutrinos, which are very "antisocial" and thus very hard to catch
B) The experiments worked OK, but they found no neutrinos at all; not a single one
C) All the neutrinos found in these experiments were one of the other two types of neutrinos, not the electron neutrino that we expect coming from nuclear fusion in the Sun
D) Now that they are working right, the chlorine experiments have found all the neutrinos that our models of the Sun have predicted should be coming
E) The chlorine experiments found only between 1/3 the number of electron neutrinos arriving from the Sun that our models predicted should be coming
