Correct option is B
Now, let's examine the answer choices:
(a) Tree : Leaves → This represents a part-whole relationship, where leaves are a part of a tree. This does not match the given relationship.
(b) Bears : Sleuth → "Sleuth" is a collective noun for a group of bears, just like "Shrewdness" is for apes. This correctly follows the pattern.
(c) Skin : Man → This shows a part-whole relationship, where skin is a part of a human body. This does not match the given relationship.
(d) Lion : Fur → This also represents a part-whole relationship, as fur is a part of a lion's body. It does not match the given pattern.
Thus, the correct option is (b) Bears : Sleuth
