The correct answer is: B. September, 1947
Pakistan engineered a massive raid into Kashmir by the tribal people on October 22, 1947. The raiders were led by Major General Akbar Khan, who was later known as the “Lion of Kashmir”. The raid was code-named “Operation Gulmarg”.
The raiders were armed with modern weapons and equipment, and they were supported by the Pakistani army. They quickly overwhelmed the Indian forces in Kashmir, and they captured the capital city of Srinagar.
The Indian government was caught off guard by the raid, and it was initially unable to stop the raiders. However, the Indian army eventually regrouped and launched a counter-offensive. The fighting continued for several months, and it eventually led to a ceasefire in January 1948.
The ceasefire line that was established in 1948 is still the de facto border between India and Pakistan in Kashmir. The Kashmir conflict is one of the most intractable disputes in South Asia, and it has been a major source of tension between India and Pakistan for over 70 years.
The other options are incorrect because they are not the dates on which Pakistan engineered a massive raid into Kashmir by the tribal people.
