c. There is no evidence to support this claim  

Explanation: -

The supernova remnant is a structure that has resulted from the explosion of a star in a supernova. It’s almost four to five billion years back and it’s pretty much long time within the universe. There is no evidence as to how the galaxy looked such a long time back  and also there are no means to verify whether supernova remnant was involved in the earth’s formation.  Also it cannot predict or verified what events happened in the galaxy during all this time. An expanding shock wave binds the supernova remnant. Until now, researchers have failed in finding out the fingerprints or evidences.  

what are the choices?
