Which expression indicates the manager's assurance in his team's capabilities?

The expression that indicates the manager's assurance in his team's capabilities is "He had every confidence." This phrase communicates a strong belief or trust in the abilities and skills of the team, suggesting that the manager fully trusts them to handle tasks and challenges effectively. It conveys a positive and supportive attitude, emphasizing commitment to the team's competence.

Other choices imply uncertainty or skepticism. For instance, "He expected every challenge" indicates preparedness but doesn't reflect confidence in the team. "He expressed every doubt" and "He conveyed every hesitation" both suggest a lack of trust or assurance, highlighting concerns rather than a strong belief in the team's performance. Thus, "He had every confidence" stands out as the best representation of the manager's assurance.
