Answer Details

How can we believe this witness when no one will corroborate his story? Explanation: The sentence is questioning the credibility of a witness's story because there is no one to support or confirm the accuracy of the story. To "corroborate" means to confirm or give support to a statement, theory, or finding. Therefore, the most appropriate option to fill the gap is "corroborate".
