Step 1: Understanding the Question:
The question asks to identify a duty of an entrepreneur from the given list of activities.
Step 2: Analysis of Options:
Let's evaluate each option to see if it represents a duty or a responsibility.
(A) Over-charging: This is the practice of charging an unfairly high price for goods or services. It is an unethical business practice, not a duty.
(B) Tax evasion: This is the illegal non-payment or under-payment of taxes. It is a criminal offense, and the opposite of an entrepreneur's duty to pay taxes honestly.
(C) Environmental pollution: Causing harm to the environment is socially irresponsible and often illegal. An entrepreneur has a social responsibility to minimize pollution, not a duty to create it.
The duties of an entrepreneur include activities like creating value, generating employment, innovating, paying taxes, contributing to economic development, and acting in a socially responsible manner.
Step 3: Final Answer:
All the given options (A, B, and C) are unethical, illegal, or socially irresponsible actions. None of them represent a duty of an entrepreneur. Therefore, the correct answer is (D) None of these.
