The complete sentences in both Spanish and English would be:
So, the correct option is:
It might be cold in September
The problem in these exercises where you have to find the best translation for a Spanish sentence is that there are sentences that might have very similar meanings to the main one but still be incorrect.
For example, here the option 'it can freeze in September' could be correct, but freeze is not the exact verb you would use to translate 'frío' in Spanish since freeze means congelado, helado. However, the use of 'it can' fits a little bit better than 'it might' when we translate 'puede'.
