Correct option is A
 The correct option to fill in the blank is (
  a) 
  cereal, serial.
  
 “Morning 
  cereal” refers to a grain-based breakfast food; a 
  serial is a TV show presented in a series of episodes. Hence, the first blank needs 
  cereal (breakfast), and the second blank needs 
  serial (TV). (Hindi: 
  cereal = अनाज/नाश्ते का दलिया, 
  serial = धारावाहिक)
  
 Example: She poured milk over her 
  cereal and switched on her favorite 
  serial.
