Your response
D.
every decade a human being will be struck by lightning
E.
every decade, a human being should be struck by lightning

IMO - D

I wasn't convenient using "should" , as it sounds like a rule. Hence eliminated A , B and E

Between C and D , C sounds like as though the same person will be struck by lightning every decade ! (i.e if he manages to survive the previous one )

Hence D

Another vote for D
