    Solution

    Some rollers are wheels (I) + All wheels are mats (A) ⇒ Some rollers are mats (I) ⇒ Conversion ⇒ Some mats are rollers (I). No belt is a rollers (E) + Some rollers are wheels (I) ⇒ Some wheels are not belts (O*) ⇒ [Probable conclusion] ⇒ No wheel may be belt (E). All wheels are mats (A) + All mats are cars (A) ⇒ All wheels are cars (A) ⇒ Conversion ⇒ Some cars are wheels (I) ⇒ [Probable conclusion] ⇒ Some cars may not be wheels (O). Hence, option 3 is correct.
    By elimination method - By 1, All + All = +ve. Hence it is eliminated. By 2, some + some = no definite conclusion can be drawn. Hence it is eliminated. By 4, No + All = -ve, Hence it is eliminated. Hence answer is option 3.
