Options that are commonly associated with bases:
- ✓ OH− — the defining species for many bases (e.g., NaOH, KOH) and produced by bases in water.
- ✓ Metal — many common inorganic bases are metal hydroxides (alkali/alkaline earth hydroxides).
- ✓ Nitrogen — many common bases (ammonia, amines) contain nitrogen with a lone pair that can accept H+.

Not associated (or not generally characteristic) of bases:
- ✗ H+ — that is the defining species of acids, not bases.
- ✗ Gas — some bases (e.g., NH3) are gases, but being a gas is not a general property of bases.
- ✗ Minerals — bases can occur in minerals but “being a mineral” is not a defining or common chemical property of bases.
