Final answer:
A governmental body in California must issue legally acceptable IDs that comply with the Real ID Act of 2005, ensuring standardized security features that align with federal law and state legislation.
Step-by-step explanation:
The entity that must issue a legally acceptable ID in California is a governmental body. According to federal law, particularly the Real ID Act of 2005, identification cards must include standardized security features, specific data, and be machine-readable. These security features are essential for boarding commercial airlines and other security-sensitive activities. California's government, like other states, must comply with these requirements when issuing driver's licenses and state identification cards. California was influenced by legal actions such as Proposition 187 and sought to accommodate legal guidelines to provide IDs under federal and state laws.
Additionally, the implementation of photo identification laws, similar to those in Indiana, necessitates that IDs display the holder's name as it appears in voter registration records, have a clear expiration date, and be issued by the state of California or the U.S. government.
