B. They are all capable of exhibiting several oxidation states
C. They are all diatomic and form divalent ions
D. They can mutually displace each other from the solution of their compounds with metals.

Explanation

All halogens are diatomic (e.g., `F_2, Cl_2, Br_2, and I_2)` and all of them form univalent ions `(F^(-), Cl^(-), Br^(-) and I^(-))`.
