13. which of the following statements about seafloor spreading is false? a. close to the mid-ocean ridge, there is almost no sediment. b. magma rises through the crust along the mid-ocean ridge. c. the oldest crust is closest to the mid-ocean ridge. d. continents move as the seafloor spreads along a mid-ocean ridge.

Option C, The oldest crust is closest to the mid-ocean ridge.

Explanation:

The oldest crust of sea floor is somewhere around 300 million years old. Mid-ocean ridges are the location where these crust are created and then they start moving away from each other. The continents are continuously moving away from each other since ages, hence it is for sure that the old crust would be very far away from  mid-ocean ridges.

Hence, option C is the correct answer

where is the option.let me know

i am going to guess that it is co2.
