If quantity is not stated in your question, then go with methamphetamine.
You think is the best answer to choose?
I am not sure, but if you have read all those links and the ones Sra posted for you, too -- and you have come to the conclusion that A is the right answer, then go with it.

If you are still unsure, you should probably bring your "lack of quantity" question up with your teacher.
