What Makes a Nonequivalent Control Group Design a Quasi-Experimental Design

What makes a nonequivalent control group design a quasi-experimental design?

A) it uses a pretest
B) random assignment is not possible
C) descriptive statistics can be used, but inferential analyses cannot be done
D) only a single group is tested
The following four questions relate to this hypothetical study:
Teachers in a local school district are given a test of computer literacy (0-100, with 100 being perfect) . Then during the school year they have monthly in-service programs designed to improve their computer literacy. Their computer knowledge is assessed again at the end of the year. Their average pretest score is 40 and their average posttest score is 80. Teachers in a comparable school district aren't given the training, but they do get the pretest and posttest.
