The correct answer is: A. Operation Polo
Operation Polo was the Indian military operation that led to the annexation of Goa, Daman, and Diu from Portugal on December 19, 1961. The operation was codenamed “Operation Vijay” (Hindi for “victory”) and was carried out by the Indian Army, Navy, and Air Force.
The operation was launched after months of diplomatic negotiations between India and Portugal failed to resolve the issue of Portuguese rule over the Indian territories. The Indian government had long argued that Goa, Daman, and Diu were an integral part of India and that Portugal’s continued presence there was a violation of Indian sovereignty.
Portugal, on the other hand, refused to relinquish its control over the territories, arguing that they were an integral part of Portugal itself. The Portuguese government also claimed that India had no legal right to the territories and that any attempt to take them by force would be considered an act of aggression.
Despite the Portuguese government’s objections, the Indian government decided to proceed with Operation Polo. The operation was launched on December 18, 1961, and was completed successfully on December 19. The Indian forces met with little resistance from the Portuguese and were able to take control of the territories without any major casualties.
The annexation of Goa, Daman, and Diu was a major victory for India and was seen as a sign of the country’s growing strength and determination to assert its sovereignty. The operation also marked the end of Portuguese rule in India and led to the establishment of diplomatic relations between the two countries.
The other options are incorrect because they are not the names of the Indian Army Operation conducted to release Goa from Portuguese rule.
