         Answer: B) Series         
         
Explanation: The trick here is to follow the structure of the statement. The blank is followed by 'of' and thus the blank will take a filler that can be followed grammatically by 'of' and also manages to give a proper meaning. On the basis of these filters, none of the options except option 2 makes any sense.
