Correct Answer:
B. 27 Oct
The correct answer is 27 Oct. Kashmir Black Day is observed on 27 October each year in Pakistan and by Kashmiris worldwide to commemorate the day in 1947 when Indian forces first landed in Kashmir following the signing of the Instrument of Accession by Maharaja Hari Singh. This day is marked as a day of mourning and protest against the Indian occupation of Kashmir. The option 26 October is incorrect because while the Instrument of Accession was signed on 26 October, the actual arrival of Indian troops occurred on 27 October. 28 October and 29 October are also incorrect dates. Therefore, 27 October is the correct answer.
