Answer: democratic leadership.
Explanation: democratic leadership has the most capability to stimulate productive discussions among group members. This is because, it encourages discussions by which new ideas are generated and problems are solved by new and perhaps better methods. The skills of the employees are polished and they are motivated because their opinions are heard and taken into consideration.
Unlike that in autocratic, in which an order is given and they have to follow it. Similarly in laissez faire, motivation is less where every decision is left on the employees.
