What does it mean to be incognito?

Being incognito refers to adopting a concealed identity or masking one's true self from others, often to avoid recognition or maintain privacy. This term is commonly used in contexts where individuals wish to go unnoticed or operate under an alias for various reasons, such as to protect themselves, seek anonymity, or observe without being recognized.

In contrast, the other options do not align with the definition of incognito: being untrustworthy implies a lack of reliability, being away from communication suggests a physical absence rather than obscured identity, and being indifferent to others denotes a lack of concern or interest, which also does not relate to hiding one's identity. Thus, option C accurately encapsulates the essence of being incognito.
