Need help with this thesis title formation

My thesis title must convey that it covers three topics:

1. Verification of compressible CFD codes


2. Verification of incompressible CFD codes


3. Residual-based mesh adaptation

Note that the first two topics are somewhat similar to each other in that they both are about verification.

Which of the following is the correct formation for the title?

(a) Verification of Compressible, Incompressible CFD Codes and Residual-based Mesh Adaptation

(b) Verification of Compressible, Incompressible CFD Codes, and Residual-based Mesh Adaptation

(c) Verification of Compressible and Incompressible CFD Codes and Residual-based Mesh Adaptation

Note the comma after "CFD Codes" in (b). Also, let's not worry about title case capitation etc. for now.

Are there any other good formations to convey the information about the three topics?

I am not an English major, so pardon any ignorance.
