Based on the chart you provided, the group that did not have veto power is the Assembly of Centuries and Assembly of Tribes.
Here's a breakdown of the groups mentioned and their powers:
- Senate: Could advise consuls and assemblies, made foreign policy, could be vetoed (implied power).
- Assemblies (Assembly of Centuries and Assembly of Tribes): They had the power to approve or veto laws, but their role did not explicitly indicate veto power like the Senate or consuls had against each other.
- Consuls: Could veto each other’s actions.
Therefore, the correct answer is that neither the Assembly of Centuries nor the Assembly of Tribes possessed veto power over actions regarding governance, compared to other entities like the Senate and consuls.
