In the year 2008, which one of the following conducted a complex scientific experiment in which sub-atomic particles were accelerated to nearly the speed of light?

The correct answer is B because the European Organization for Nuclear Research, commonly known as CERN, operates the Large Hadron Collider. In September 2008, CERN officially started the Large Hadron Collider, which is the world largest and most powerful particle accelerator. The experiment involved accelerating beams of protons to nearly the speed of light and colliding them to study the fundamental particles of the universe. While the other organizations are involved in space exploration or atomic energy regulation, CERN is specifically dedicated to high-energy physics and the operation of the particle accelerator located on the border between France and Switzerland.
