Which of the following best describes a novice?

The term "novice" is defined as someone who is new or inexperienced in a particular activity or field. This designation emphasizes a lack of familiarity or skill, typically associated with those who are just starting to learn or engage with a subject. In this context, option B highlights that a novice is characterized by their inexperience, making it the best description among the choices provided.

The other options imply a level of proficiency or commitment that does not align with the definition of a novice. A skilled expert and a leader in their field suggest a high degree of competence and experience, clearly opposite to the idea of being a novice. Meanwhile, an avid supporter indicates a level of enthusiasm or loyalty, which also does not pertain to the concept of inexperience. Thus, option B accurately conveys the essence of what it means to be a novice.
