43. Ridge with slowest rate of seafloor spreading.   

44. Ridge with moderate rate of seafloor spreading.

45. Ridge with fastest rate of seafloor spreading

Options:

A. Shivering Sea Ridge (A-A’)

Explanation / Answer

43 - A

44 - B

45 - C

I think the Sunset sea ridge has travelled largest distance in similar time period as of other two ridges, thus velocity being the highest.
