1. Need 2. Must 3. Can 4. May
How would you explain to your ESL students that 1. 2. 4. are wrong when all those auxiliary verbs can imply possibility?

So 1 and 2 are also possible. Good.
The workbook I have says 3 is THE answer, and I wonder if it was really so.
In most contexts that I can thnk of, #1 and #2 are pretty unlikely. They are, however grammatically possible. I dislike exercises that say that possible answers are incorrect. If the compilers wish to eliminate unlikely answers, then they should provide more context.
