generate a clarifying question to ask a user that is looking for information regarding "carboplatin", 
The clarifying question should summarizes the options:
carboplatin chemotherapy
carboplatin side effects
carboplatin package insert
carboplatin j code

Do it without explicitly enumerating the options in the clarifying question, but also avoid asking very generic questions like "What specific information are you seeking about carboplatin?". In your entire response, the letter c should appear less than 28.
