Answer:
1. Not a bad idea, is it?
2. That is the gentleman, isn't it?
3. You learn German, Don't you?
4. She is the new School Prefect, Isn't she?
5. She can jump the hurdle, can she?
C. A request for transcripts
The correct answer is -ic.
When you add the suffix -ic to the root phon, you get the word phonic, which means 'something that has the characteristics of sound.' If you add the suffix -al to phon to create phonal, it means something related to sound, which is not the exact same meaning (so that is a wrong option).
Words phonen and phonly don't exist, so -en and -ly are wrong options as well.
