The correct answer is C. sad, evolve.
The word “sad” is used to describe something that is causing or feeling sorrow or regret. In this case, the speaker is expressing sadness that 40 years after independence, India has not yet been able to develop a suitable education or examination system.
The word “evolve” means to develop or change gradually over time. In this case, the speaker is suggesting that India’s education and examination system has not been able to keep up with the changing needs of the country.
The other options are incorrect because they do not accurately reflect the speaker’s sentiment. The word “bad” is too strong, and it suggests that India’s education and examination system is completely worthless. The word “improper” is too negative, and it suggests that India’s education and examination system is somehow wrong or unethical. The word “objectionable” is too strong, and it suggests that India’s education and examination system is somehow offensive or harmful.
In conclusion, the correct answer is C. sad, evolve.
