Got D band if ask release from the project they will release??

It depends on the project.
If you want release just speak to your manager and say you are disappointed with rating you got and can you upgrade to B. If he says no your performance not good then say you did your best and if you think my performance not good then please release me so i find project which will value my work and skills

Yes

Getting D band we cannot work in the same project we need ask and get it released
