B Correct answer
Explanation

Radio-active is the correct spelling - describing materials that emit radiation. 'Radio' is spelled with 'dio' not 'deo' (Radeo), and 'active' uses 'ac' not 'acc' (Radioacctive). The hyphen connects the compound adjective correctly, though 'radioactive' as one word is also acceptable.
