Correct Answer - Option 3 : Being courageous and exhibit leadership qualities
A good police personnel must be courageous and exhibit leadership qualities.
A person who is timid i.e., lacks in courage or self-confidence cannot be a good police personnel. A police personnel has to face various situations day to day where he has to show courage.
A person who jumps to conclusions cannot be a good police personnel. A good police personnel must rely on facts and evidence and then make a conclusion based on them.
A person who is ready to oppress all forms of opposition cannot be a good police personnel. The duty of a good police personnel is to maintain law and order, work for the welfare for the people and catch the criminals. Exercising their power in an unfair way is something just opposite to what a good police personnel would do.
Hence, 'Being courageous and exhibit leadership qualities' is the correct answer.
