Best Answer Explained in Below-:

The correct answer is C) Russia, as it was one of the first countries to successfully test-launch a hypersonic aircraft. In December 2019, Russia conducted successful tests of its Avangard hypersonic glide vehicle, marking a significant milestone in hypersonic technology. This system is capable of traveling at speeds exceeding Mach 5, which is five times the speed of sound, allowing it to evade traditional missile defense systems.

Hypersonic aircraft and missiles are designed to fly at ultra-high speeds and altitudes, making them difficult to detect and intercept. Russia has invested heavily in hypersonic technology, reflecting its strategic priority to maintain military superiority. The Avangard’s successful test-launch demonstrated not only the technological capabilities but also a robust defense strategy aimed at countering NATO and other adversaries.

While countries like the United States, China, and India are also developing their hypersonic technologies, Russia stands out for having completed successful tests and integrating such systems into its military arsenal earlier. Hence, the achievement of Russia in this domain is why it is the correct answer to the question.
