Certainly not intrinsic or astronomical or experimental (because astronomical theories, unlike theories of physics or chemistry are not based on experiment, but are based on observation). The phrase 'superfluous interest' does not convey any meaning to the given sentence. "That the modern scientists consider the outdated Greek theory as of only historical interest" completes a cogent sentence So, (A) is the answer
