🎥 Video solution / Text Solution of this question is given below:
From “Some cakes are jewels” and “All jewels are rings” ⇒ those cakes are rings ⇒ “Some rings are cakes” is definitely true ⇒ Conclusion II follows.
From “Some rings are necklaces” and “All jewels are rings” we cannot be sure that the necklaces are jewels, so I does not follow.
“No jewel is necklace” is also not forced; it might be true or false, so III does not follow.
