The supernova event of 1987 is interesting in that there is still no evidence of the neutron star that current theory says should have remained after a supernova of that size. This is in spite of the fact that many of the most sensitive instruments ever developed have searched for the tell-tale pulse of radiation that neutron stars emit. Thus, current theory is wrong in claiming that supernovas of a certain size always produce neutron stars. Which one of the following, if true, most strengthens the argument?
A: Most supernova remnants that astronomers have detected have a neutron star nearby.
B: The supernova of 1987 was the first that scientists were able to observe in progress.
C: Several important features of the 1987 supernova are correctly predicted by the current theory.
D: Sensitive astronomical instruments have detected neutron stars much farther away than the location of the 1987 supernova.
Choose A, B, C or D as your solution.
