Answer:
C. is the correct answer. Sea level, Pacific Ocean, 1955 to 1975.
Explanation:
Letter C is the correct link because you are looking for the change in the height of an ocean over a 20 year period of time.
The reason for this is because A only has names of oceans, therefore wouldn't help you find the changes in height or the number of years. B has volume, density, and temperature, but you are not trying to find the mass of the ocean. Finally, D has the wind speed, pH, and salinity, and you are not looking for any of those.
Hope this helps! PLZ Mark Brainliest and friend me, bro! ;)
