Control Quality is internal process but Accepting Deliverables involves client. So they are not same. 

Yes if you take acceptance from client it will be Validate Scope process and it can be for interim deliverables also. 

The deliverables produced from Direct and Manage Project Work goes through Control Quality process.This in turn gives Validated deliverables.

Saket : This was a problem with PMBOK 4, now PMBOK 5 clearly says that Quality Control should produce Verified Deliverable.

In the Validate Scope process we see Verified deliverables as an input to give the accepted deliverables.

Saket : This statement is right, Verified Deliverable is an input and Accepted or Validated Deliverables are output of Validate Scope.

Qn.1 Is this the same Validated deliverables from Control Quality??

Saket : No , its verified.

Qn.2 Rita's process chart,in the M&C process group talks about gaining acceptance of interim deliverables from customer. Is this the Validate Scope process??Is this done by the stakeholders because it is validation(acceptance by sponsor)??

Saket: Yes
