Answer:
a) the leader presents ideas and invites questions.
Explanation:
Leadership continuum is a leadership style which describes the relationship with respect to the autonomy that a manager gives to his subordinates, and the level of authority used by him/ her. This is a inverse proportional relation which reduces the authority of the manager when team's freedom increases. It debases an autocratic rule by a manager, especially in taking decisions.
The example cited in the question is a way of taking decision by suggestions by expecting questions from his team.
