The correct execution schedule must account for both the priorities and the dependencies. Test cases with high priority should be executed first, but their dependencies must be respected. Starting with TC1 addresses the dependency of TC3 (which is high priority). Then, TC3 can be executed since TC1 has already been completed. TC2 must be executed before TC4 due to its logical dependency, which is also high priority. TC6, being medium priority, comes next, and finally TC5, which is low priority, is executed last. This ensures all dependencies and priorities are respected.
