Final answer:
Sue's management style is controlling (option C) or authoritarian, characterized by top-down communication and directive leadership required in emergency situations for efficiency.
Step-by-step explanation:
During a code, when Sue begins giving orders to the staff, her management style is controlling. This style is also known as authoritarian, where the communication pattern flows from the top down. Sue's approach is directive and focused on quick decision-making and clear directive leadership, often necessary in emergency situations to ensure that objectives are met efficiently. This can be contrasted with other leadership styles such as democratic, which encourages group participation; laissez-faire, which is more hands-off; and participative, which involves the team in decision-making processes.
