Final answer:
Tangential regarding disrupted thought processes means going off on a tangent and not addressing the main point, resulting in straying away from the central theme in speech or writing.
Step-by-step explanation:
The term tangential regarding disrupted thought processes/content refers to option a) Going off on a tangent and not addressing the main point. When someone is tangential in their thinking or speech, they tend to stray away from the main topic, often bringing in irrelevant or loosely connected ideas without returning to the central theme.
This can result in conversations or writings that seem disjointed, and it is a concept that may be explored in subjects such as psychology and cognitive sciences. Tangential thinking is different from divergent thinking, the latter allowing a person to explore many different ideas and solutions creatively, but still within the bounds of relevance.
