The answer is Option B. Each cycle of spreading and intrusion of magma during seafloor spreading results in a new ocean crust.
Over the length of an ordinary human lifetime, the surface of the Earth seems to remain largely unchanged. According to Wegener's theory of continental drift, the continents of Earth were originally connected to form a single landmass. Around 200 million years ago, the Pangaea supercontinent, which included all seven landmasses, existed.
Most people, including many scientists, believed that the ocean floor, unlike the continents, was largely flat until the middle of the 20th century. However, technological developments in the 1940s and 1950s disproved all of these generally held beliefs. Wegener's model of continental drift was incomplete without the inclusion of seafloor spreading.
Magma rises and hardens to form a new crust during seafloor spreading, which becomes a component of the ocean floor. Another little area of the ocean floor is formed as a result of each cycle of spreading.
