First identify the adjective clause.  Which part has the adjective in it, do you know?

If you look at the end of the sentence you will see "Great inspiration to me"  This word "inspiration" is the adjective because it is describing Einsteins theory.  It is describing what it does for the person therefor it is A, Possessive.
