What is the meaning of 'Espirit De Corps'?

The correct answer is option (3)- It is unity and harmony among employees.

Esprit De Corps: Management should promote a team spirit of unity and harmony among employees, according to Fayol. Management should promote teamwork especially in large organisations because otherwise objectives would be difficult to realise. It will also result in a loss of coordination. A manager should replace 'l' with 'We' in ail his conversations with workers to foster team spirit. This will give rise to a spirit of mutual trust and belongingness among team members.
