n(A) = 21                                                                                                      

n(B) = 26                                                                            

n(C) = 29 

n( A \cap B) = 14

n( A \cap C) = 12

n (B \cap C ) = 14

n( A \cap B \cap C) = 8

      n(liked product C only) = 29 - 4 -8 - 6 = 11

11 people like only product C.
