Why is this answer correct?

In Saxony-Anhalt, people may vote in local elections from the age of 16; the state's local election law permits this age. 14 is too young, 18 applies to Landtag and Bundestag elections, and 20 is not a voting age.

Into the local election booth at 16 – in Saxony-Anhalt.
