Final answer:
None of the provided selections directly deal with India's war with Pakistan; 'Quit India' by Gandhi is focused on independence from British rule.
Step-by-step explanation:
The question pertains to selections that deal with India's war with Pakistan. Mahatma Gandhi's "Quit India" speech focuses on India's struggle for independence from British colonialism using non-violent resistance and does not deal with India's war with Pakistan. V. S. Naipaul's "The Union of Indian States" and Paul Theroux's "The Great Indian Railway Bazaar" have not been detailed in the provided information, so their relevance cannot be determined.
Therefore, based on the information given, the correct answer to which of the shorter selections deal with India's war with Pakistan is (a) None of the selections.
