According to late business professor Warren Bennis, leaders differ from managers in that leaders are concerned with doing the right thing.

Option a

Explanation:

A leader is "an individual who determines the accomplishment of a goal by a group of people." 3P's – individuals, parties and reasons as shown in the accompanying example – would have been a short word for this description.

A leader by his significance is someone who leads by example and leads everyone else to follow. This is a fundamental requirement. Being a leader a person has to devote himself profoundly to the goal of achieving it, although no one follows them!

An effective leader is an individual with a greater passion for a purpose. Somebody with a goal and a vision that will make society stronger. Therefore, without ambition, a leader would not make and execute the requisite brave and challenging choices.
