Explanation:
Nicola is displaying the decision-making style known as autocratic. This is because she is not asking for input or advice from employees, and instead makes the entire decision herself. Therefore, she is taking complete control over the situation by doing so and also taking full responsibility of both the situation and the possible consequences that may arise from the decision that she has made.
