According to the article, scientists can use sound to measure the changing temperature of the ocean. Which paragraph BEST supports this idea?(A)"So it's really important to track that energy in the climate system and track the warming of the ocean,"says Jörn Callies, an oceanographer at the California Institute of Technology.(B)Temperature also affects the speed of sound. Particles at higher temperatures have more energy andallow sound waves to travel more quickly. This means that sound travels faster in warmer water thancolder water and these differences in sound speed can reveal changing temperatures.(C)Scientists originally proposed using sounds produced by machines to measure ocean warming, but itwould impact marine animals, such as whales, that use sound to communicate. However, Wu and hiscolleagues showed they could use the natural sounds produced by earthquakes instead.(D)A fraction of a degree may not sound like a lot, but it represents a huge amount of heat. That's becauseit's the change in a body of water almost 3,200 kilometers (2,000 miles) wide and several kilometersdeep.2
