The argument aims to disprove the hypothesis that our solar system was formed from a supernova by stating that researchers have found no iron-60 in meteorites formed early in the solar system's history.
For the argument to hold, it must assume that if iron-60 were present in the early history of the solar system, it would indeed be found in meteorites formed early in the solar system's history. This assumption is necessary to link the absence of iron-60 in early meteorites to the absence of iron-60 in the early solar system, which, in turn, supports the argument's conclusion.
Therefore, the correct answer is (E): If there had been iron-60 present in the early history of the solar system, it would be found in meteorites formed early in the solar system's history.
