Final answer:
The correct option is c. In the 'Quit India' speech, Gandhi does not mention a specific book he read in prison; however, he often referenced the Bhagavad Gita in other contexts. The speech itself centers on non-violent resistance and Gandhi's commitment to lead India to independence through peaceful methods.
Step-by-step explanation:
In his "Quit India" speech, Mahatma Gandhi does not explicitly mention reading a particular book while in prison. The speech is primarily focused on the strategy of non-violent resistance or ahimsa against British colonial rule to achieve Indian independence.
However, Gandhi was known to draw inspiration from various religious texts, such as the Bhagavad Gita within the epic Mahabharata, which he often referred to in his writings and speeches. This speech emphasizes the use of non-violence as a powerful tool for resistance and outlines Gandhi's sense of duty to his people to lead them towards independence. He believes in carrying out this duty through peaceful means, in accordance with his ethical principles.
