Compare and replace colomuns with names

As a result, I want the names in column A (with matching value in B) in column C. An additional problem is that there are more names in column A than in column C.
These extra names may be removed. So the important thing is that e.g. A: Aberasturi J. & B:4; A: J. Aberasturi & B: 4 becomes.

Thanks in advance!
