If a person claims not to know what is in their own pants pocket, what might this indicate?

Claiming not to know what is in one's own pants pocket can suggest a conscious effort to conceal something. When individuals make such statements, especially in a law enforcement context, it can raise suspicions that they might be attempting to hide illegal items, such as drugs. This behavior can signal a potential intention to evade legal scrutiny or responsibility for items that could have severe legal implications.

The other options, while they may describe possible states of mind, do not directly connect to the context of concealing something. Nervousness, confusion, or being truthful may explain the behavior, but the act of not knowing what is in a pocket typically leans more towards a deliberate effort to hide information rather than a genuine lack of awareness or honesty. Thus, option B directly correlates with a behavior often associated with concealment in legal scenarios.
