One hour ago the time was $$12:15$$ P.M.; two hours ago the time was $$11:15$$ A.M.; three hours ago the time was $$10:15$$ A.M. Three and one-half hours ago the time was $$9:45$$ A.M. 
If the correct time now is $$1:15$$ P.M., and if my clock stopped running three and one-half hours ago, when did it stop running? 
Options:
(A) $$8:45$$ A.M. 
(B) $$9:45$$ A.M. 
(C) $$10:45$$ A.M. 
(D) $$4:45$$ P.M.
