The main differences between a software process assessment and a software
capability evaluation are:

A.
Software process assessments and software capability evaluations are
essentially identical, and there are no major differences between the two.

B.
Software capability evaluations determine the state of an
organizations current software process and are used to gain support
from within the organization for a software process improvement
program; software process assessments are used to identify
contractors who are qualified to develop software or to monitor the
state of the software process in a current software project.

C.
Software process assessments are used to develop a risk profile for
source selection; software capability evaluations are used to develop
an action plan for continuous process improvement.

D.
Software process assessments determine the state of an
organizations current software process and are used to gain support
from within the organization for a software process improvement
program; software capability evaluations are used to identify
contractors who are qualified to develop software or to monitor the
state of the software process in a current software project.

Explanation:
The other answers are distracters. If, in
answer “Software process assessments are used…” the terms software process assessments and
software capability
evaluations were interchanged, that result would also be correct.
It would then read, Software capability evaluations are used to develop
a risk profile for source selection; software process assessments are used
to develop an action plan for continuous process improvement.
