Which of the following in non-verbal communication can indicate truthfulness?

In non-verbal communication, all of the listed elements—gestures, facial expressions, and eye contact—can play significant roles in indicating truthfulness.

Gestures can communicate confidence and transparency, especially when they align with verbal messages. For instance, open hand gestures may suggest honesty, while closed hands can imply defensiveness or concealment.

Facial expressions provide immediate insight into a person's feelings and intentions. A genuine smile, for instance, often indicates honesty, while a lack of expression or forced smiles may raise suspicions about the truthfulness of the individual.

Eye contact is a crucial component of communication; it can demonstrate sincerity and engagement when a person is truthful. Maintaining appropriate eye contact typically fosters a sense of trust and openness, whereas avoidance of eye contact may imply deception or uncomfortable truths.

Since all these forms of non-verbal communication can be indicators of truthfulness when appropriately interpreted in context, it is correct to say that they collectively help convey honesty in interpersonal exchanges.
