Step 1: Understanding inorganic benzene.
Inorganic benzene is borazine, which has structural analogy with benzene and is represented as \(B_3N_3H_6\).
Step 2: Structural similarity.
It consists of alternating boron and nitrogen atoms forming a छह-membered ring similar to benzene.
Step 3: Bonding nature.
It shows delocalization of electrons, making it aromatic in nature similar to benzene.
Step 4: Identification.
Among given options, only \(B_3N_3H_6\) matches borazine structure.
Step 5: Final conclusion.
Thus, inorganic benzene is borazine.
Final Answer:
\[
\boxed{B_3N_3H_6}
\]
