B. Boron and Aluminum have similar chemical behavior because they belong to the same group on the periodic table.
Elements in the same group have the same number of valence electrons (both B and Al are in Group 13 with three valence electrons), which leads to similar chemical properties (e.g., similar common oxidation states and bonding patterns).
