Final answer:
Chris, known for his assertive and confrontational style, is more aligned with Authoritarian Leadership, which focuses on directive, goal-orientated behaviors without much input from others.
Step-by-step explanation:
Based on the description of Chris, the CEO of a software firm, being assertive, engaging in confrontational dialogue, and displaying a forceful, confident, and somewhat arrogant demeanor, it is most likely that he would prefer Authoritarian Leadership. This style is characterized by issuing orders and assigning tasks with little to no feedback from group members.
Business leaders like Mark Zuckerberg are often cited as examples of authoritarian leaders because of their strong focus on meeting goals. In contrast to Democratic Leadership, which involves consensus building and group participation, or Transformational Leadership and Servant Leadership that require empowering followers and putting their needs first, Chris's behavior aligns more with the top-down approach of Authoritarian Leadership.
