Which of the following best defines the word 'fledgling'?

The word 'fledgling' refers to a young bird that has just acquired its feathers and is learning to fly, symbolizing something that is in the early stages of development or lacks maturity. In a broader context, it is often used to describe an inexperienced person who is new to a particular field or activity. This captures the essence of the term, emphasizing the notion of youthfulness and the process of gaining experience over time. The other options do not align with this definition, as they suggest either expertise, focus on debate, or legislative processes, which are unrelated to the concept of being inexperienced.
