Refer to the exhibit, which shows the partial output of FortiOS kernel slabs. Which statement is true?

The correct answer is D. The total slab size of the tcp_session slab is 7500 kB and is associated with the kernel. The tcp_session slab holds five 1,500 B objects in one slab (1,500 B × 5 = 7,500 B) and its slabdata flags indicate it's a kernel‑allocated slab.
