The correct answer is (a) 16th November.
National Journalism Day is celebrated on 16th November every year in India. It is a day to commemorate the birth anniversary of Mahatma Gandhi, who was also a great journalist. He used journalism as a tool to spread his message of peace and non-violence. He also used it to expose the atrocities of the British rule.
The first National Journalism Day was celebrated in 1961. It was a day to pay tribute to the journalists who have played a significant role in the development of India. The day is also celebrated to promote the freedom of the press and to encourage journalists to uphold the highest standards of ethics and professionalism.
The other options are incorrect because they are not the birth anniversary of Mahatma Gandhi.
