The selected option is incorrect. Please tell me the right answer with an explanation, thanks.

Which of the following statements about slab caches is correct? (Assume a slab such as the one discussed in the lecture.) The slab allocator sits on top of the buddy allocator. If the smallest chunk that can be allocated via buddy is 4KB, that is also the maximum size for a slab, regardless of object size. The slab allocator sits on top of the buddy allocator. If the smallest chunk that can be allocated via buddy is 4KB, that is also the smallest object size for a slab. The slab allocator sits on top of the buddy allocator. If the smallest chunk that can be allocated via buddy is 4KB, slabs with internal descriptors can only be multiples of 4KB in size and only hold objects that are less than 4KB in size. Slabs can be larger than the smallest allocation size offered by the buddy allocator. Whatever the size, it cannot contain objects that are larger than the slab size
