The presidential form of government consists of the following characteristics:
1. Fixed term of office: In a presidential system, the president is elected for a fixed term of office, usually for a specific number of years. This means that the president serves a set period of time in office and cannot be easily removed before the end of their term.
2. No overlap in membership between the executive and the legislature: In a presidential system, there is a clear separation of powers between the executive (president) and the legislature (parliament or congress). There is no overlap in membership, meaning that members of the executive branch cannot also be members of the legislative branch.
3. Popular election of the President: In a presidential system, the president is elected by the people through a popular vote. This means that the president derives their legitimacy from the support of the public.
Therefore, the correct answer is option 4, as all of the mentioned characteristics are present in a presidential form of government.
