Bavaria’s state parliament is elected for five years.

First ask which body is being elected.

The Landtag is the parliament of the Free State. An electoral term describes the period of an elected parliament until the next one. For Bavaria, learn the connection Landtag → five years; the number describes neither voting age nor the number of members.

The constitution also specifies how time is counted: the term begins when parliament first meets and ends when the new parliament meets. The regular new election falls 59 to 62 months after the previous election. Five years therefore does not mean every election must fall on the same calendar date.

The other three answers

Assess the offered numbers in relation to the body named in the question.

The regular term is not a guarantee against every early election.

Article 18 permits dissolution before the term expires in certain circumstances, including an appropriate majority decision by the Landtag itself. The catalogue question nevertheless asks for the statutory regular term.

A change in a government office is also not the same as a new state parliamentary election. Parliament, government and individual officeholders are different things. The number 5 here relates to the election of parliament.
