D. 60
Ans : C

To determine the correct answer, we need to find information on the percentage of current carbon dioxide emissions that have been absorbed into the oceans.

One way to approach finding this information is to conduct a search using a reliable search engine, such as Google. You can type in the keywords "percentage of carbon dioxide emissions absorbed by oceans" or a similar phrase.

Upon conducting the search, you may come across various sources, such as scientific research papers or reports from organizations that focus on climate change and the environment. These sources often provide information and statistics related to carbon dioxide absorption by the oceans.

By examining the sources, you can determine the correct answer. In this case, the correct answer is C. 50 percent, indicating that approximately 50 percent of current carbon dioxide emissions have been absorbed into the oceans.
