Deferred correction procedure for high-resolution schemes leads

Deferred correction procedure for high-resolution schemes leads to __________

A. NVF and TVD

B. NWF and DWF

C. NVF and DWF

D. TVD and NWF

I have been asked this question in homework.

The above asked question is from Deferred Correction for High-Resolution Schemes in chapter High Resolution Schemes of Computational Fluid Dynamics

Correct answer is B. NWF and DWF

For explanation I would say: The convergence problem of the high-resolution schemes paved the way for techniques of implementing high-resolution schemes that are more implicit such as NWF and DWF.
