The correct answer is (b), Webb Miller.
Webb Miller was an American journalist who covered the Dandi March for the United Press. He was one of the first reporters to witness the march and his reports helped to raise awareness of Gandhi’s campaign for Indian independence.
H. N. Brailsford was a British journalist who also covered the Dandi March. He was a supporter of Gandhi’s movement and his reports were sympathetic to the Indian cause.
G Slocomba was an American journalist who was not present at the Dandi March. He wrote a book about the march after it was over, but his account was based on secondary sources.
James Patterson was a Scottish journalist who was also not present at the Dandi March. He wrote a book about the march after it was over, but his account was based on secondary sources.
Webb Miller’s reports were the most accurate and objective of the four journalists. He was present at the march and he interviewed Gandhi and other participants. His reports helped to shape public opinion in the United States and around the world.
