What describes the behavior that is impacted by external conditions?

The correct choice provides an important concept in understanding how behavior is influenced by the environment. Environmental or ecological factors encompass the conditions and variables in an individual's surroundings that can affect their behavior. This includes elements such as physical surroundings, social contexts, cultural norms, and environmental changes, all of which can play a significant role in shaping how a person behaves in different situations.

When discussing behavior, it is important to acknowledge that ecological factors can lead to variations in responses based on changes in the external environment. For instance, the stressors found in a person's immediate environment, such as loud noise or social interactions, can profoundly impact behavior and decision-making.

By focusing on ecological factors, we recognize the complex interplay between an individual and their environment, and how these influences can lead to different behavioral outcomes.
