I have a multiple choice question that might have only one answer or all of the above might be correct. Since I'm teaching kids I want to avoid wordiness, below are my two attempts:

or...
What is/are the differences between a base 10 counting system and a base 16 counting system?
Does anyone have a better approach to this? I feel there must be!
