Step-by-step explanation:
In the context of individual barriers, credibility problems arise when consistency is lacking. This is because credibility is closely tied to the reliability and predictability of information or behavior. When individuals or sources of information demonstrate inconsistency, their credibility is questioned. Such issues with credibility can be a significant barrier to effective communication and trust establishment.
For instance, in the domain of social studies, when evaluating the trustworthiness of various information outlets, a key step is to assess their consistency. Moreover, in an educational setting, consistent communication can help bridge cultural and socio-economical barriers, allowing for better understanding and reducing miscommunication between teachers and students of different backgrounds.
Testimonial injustice also relates to credibility problems as it involves unfairly considering an individual's or group's opinions as untrustworthy. In belief systems, when qualifiers and alternative interpretations are added extensively to explain away discrepancies, it challenges the system's credibility and can lead to a reevaluation or change in beliefs.. option c is answer
