Which Javanese speech style is used when speaking to social superiors?

The Javanese speech style used when speaking to social superiors is known as Krama (or Kromo).12

As a member of the Austronesian language family, Javanese utilizes distinct status styles to reflect social stratification. While ngoko is the informal style used for social equals or inferiors, krama serves as the deferential or polite form required for interactions with those of higher social standing. Additional variations exist, such as madya (a middle style) and krama inggil (a highly deferential form).324
