II. Some colours are pencils → True (As All pencils are colours so, Some colours are pencils is true)
III. Some papers are pens → True (As All pens are papers so, Some papers are pens is true)
∴ Here, Only conclusion II and III are true.
Hence, the correct answer is "Only conclusions II and III follow".
