Step 1: Spot the clue:
The words fearlessly expose popular defects and arouse desirable sentiments show a moral view of the press. This points to a leader who used newspapers for reform and ethics.
Step 2: Link the clue to a person:
Gandhi edited his own weeklies and kept them free of advertisements. He wrote that a newspaper should serve people and truth. The three-point list of objectives comes from his own account of his journalism.
Step 3: Rule out Nehru:
Nehru is linked with the National Herald as a nationalist paper. He did not leave this classic three-aim statement. So option 2 is out.
Step 4: Rule out Patel:
Patel worked mainly in politics and administration, not as a theorist of the press. Option 3 is out.
Step 5: Rule out Roy:
Roy fought for press freedom in the early 1800s, but the quote is about the role of a newspaper in the freedom struggle era and belongs to Gandhi. Option 4 is out.
Final Answer:
Option 1 is correct, and the quote is from Gandhi's own account of his work in journalism.
\[ \boxed{\text{Mahatma Gandhi}} \]
