The best practice for establishing credibility and conveying empathy with stakeholders during discovery sessions is to ensure the workshop schedule considers time zone and language differences. This shows respect and sensitivity to the stakeholders' preferences and needs, and helps to avoid potential misunderstandings or conflicts. It also helps to build rapport and trust with the stakeholders, and encourages their participation and engagement. The other options are either irrelevant or ineffective. Option A does not address the stakeholders' needs or expectations, and may come across as boastful or arrogant. Option C does not convey empathy or understanding, and may be too repetitive or boring.
