Best Answer Explained in Below-:

The term "insurgent" refers to someone who rises in revolt against an established authority, often in a political or social context. The core of the word implies a rejection of the status quo and an active challenge to established governance or norms. This inherently aligns with the concept of being "rebellious," as both terms communicate a sense of defiance and a desire for change or upheaval.

Option B, "Rebellious," captures this essence perfectly, as it denotes a willingness to resist or oppose control or tradition. In contrast, the other options—A) Loyal, C) Sincere, and D) Confident—fail to encapsulate the fundamentally oppositional nature of an insurgent. Being "loyal" suggests adherence and support for authority, while "sincere" implies honesty without any inherent opposition. "Confident," while possibly relevant to a rebellious individual, lacks the explicit connotation of defiance toward authority.

Thus, Option B clearly embodies the spirit and actions associated with being an insurgent, making it the correct choice.
