Two aspects of insurgency are components and what other aspect?

The correct choice highlights the concept that insurgency is composed of not just specific components but also its manifestation within society and conflict. The manifestation aspect refers to how insurgents express their goals, ideologies, and methods through various activities and actions in the socio-political landscape. Understanding insurgency involves recognizing these manifestations, as they are critical in shaping both the perception of the insurgency by the populace and its effectiveness in achieving objectives.

In contrast, components typically refer to the structural elements or characteristics of an insurgency, while activities relate to the specific actions taken by insurgents. Resistance might pertain to the pushback against the insurgency, and identity could refer to how groups involved in an insurgency define themselves. However, manifestation encompasses the broader and more dynamic representation of the insurgency, which is pivotal to comprehending its impact and potential success.
