Answer:
The correct answer is: Some elements of the theory have not yet been investigated.
Explanation:
The goal-path theory can be defined as a theory that states that a leader has the ability to directly influence his subordinates to change their perceptions and achieve objectives and goals both professionally and personally. Therefore, according to theory, the leader is the one who helps subordinates to find ways to achieve goals and influence their behaviors, motivations and satisfactions.
So even though the goal-path theory has received more research support than other leadership model theories, a problem associated with the theory is that there is no complete evidence of its effectiveness, so it is correct to say that the multiple choice of some elements of the theory has not yet been investigated.
