B Only I and II follows Correct Answer Incorrect Answer
C Only I and III follow Correct Answer Incorrect Answer
D Only II and III follows Correct Answer Incorrect Answer
E None follows Correct Answer Incorrect Answer

Solution

Some Balloon are String (I) → Conversion → Some String are Balloon (I) + All Balloon are Colour (A) → Some String are Colour (I) → Conversion → Some Colours are String (I). Hence conclusion I follows. Some Strings are Scales (I) + All Scales are Toffee (A) → Some Strings are Toffee (I) → Probable Conclusion →  All Strings can be Toffee (A). Hence conclusion II follows. Some Balloon are String (I) + Some Strings are Scales (I) → No conclusion. Hence conclusion III does not follow.
