Runes are which of these?

The choices given are misleading. Are runes what the symbols are called or are runes the stones with the symbols on them? Or is it interchangeable? Would I ever find runes on a roadsign? in a magazine? on my tv screen?

Some people use rune stones or symbols for divination.

runes are a little world-wide but still older than our forefathers

the symbol for Bluetooth is made up of the runes that spell the name.

Runes runes that's weird though
