What Are the Differences Between the Simple Quasi-Experimental Pretest-Posttest Design

What are the differences between the simple quasi-experimental pretest-posttest design and an experimental version of the same design with a control group, in which there is random assignment to group?

A) This experimental design controls for the effects of more extraneous variables than does the quasi-experimental one.
B) Subjects are blind to group assignment in the experimental design but not in the quasi-experimental design.
C) In the experimental version, there is better construct validity.
D) This experimental design controls for the history threat to internal validity, whereas the quasi-experimental one does not.
E) This experimental design controls for the testing threat to internal validity, whereas the quasi-experimental one does not.
