Choose the correct option.
If 'inter' means between as in interstate, 'intra' as in intravenous means _________.
This question checks if you know how the prefix intra works compared to inter. The best way to solve it is to test each option against the actual word intravenous.

Let's summarize:
So the blank should read "within," making option 3 the answer.
