Borazine ((BH)₃(NH)₃) is an inorganic compound which has three alternating units each of B - H and N - H. Boron (B) and Nitrogen (N) in Borazine are both having sp2 hybridization. Each of the Boron atoms has an empty p-orbital. The orbitals in Boron are hybridized to the sp2 configuration where boron tends to form bonds with any three other atoms.
Boron atom in Diborane has an sp3 hybridization. The bonding of the Boron atom with the hydrogen atoms and other boron atoms in Diborane is different from that of the normal Boron atoms. In Diborane, the 2 Boron atoms form the three-centre 2-electron bonds, which is also called as the Banana bonds. Each bond involves 1 Boron atom and 2 Hydrogen atoms. The 2 Boron atoms are connected by another B-H-B bond.

Answer:
In diborane boron is involved in sp3 hybridisation while in borazine it is in sp2 hybiridisation.
