The correct answer is option 4: administrative as well as quasi-judicial and quasi-legislative functions. The bureaucracy performs a range of functions that go beyond just administrative tasks. Administrative functions involve tasks like implementing policies and managing day-to-day operations. However, the bureaucracy also has quasi-judicial functions, which involve making decisions similar to those made in a court of law, such as resolving disputes or imposing penalties. Similarly, the bureaucracy has quasi-legislative functions, which involve creating rules and regulations that have the force of law. These functions allow the bureaucracy to act as an executive, judicial, and legislative body, making it an important and complex institution within the government. It is responsible for not only the execution of policies but also the enforcement and creation of laws and regulations.
