Final answer:
According to Fiedler's contingency model, a leader's behavior cannot be changed with the situation, so the answer is B. False. Instead, the situation should be adjusted to match the leader's fixed leadership style.
Step-by-step explanation:
The question relates to whether a leader's behavior can be changed based on the situation according to Fiedler's contingency model. The answer to this question is B. False. Fiedler's contingency model is grounded on the premise that a leader's effectiveness is contingent upon the interplay between the leader's style of leadership and the favorableness of the situational context. Fiedler suggested that leadership style is fixed and what should be changed to achieve effective leadership is the situation to match the leader's style. Therefore, a leader does not change their behavior with the situation but rather the environment is modified to suit the leader's innate style.
