Where,
X = the exposure of a group to an independent variable,treatment,event,the effects of which are to be determined
O = the process of observation or measurement of the dependent variable on the test units or group of units
R = the random assignment of test units or groups to separate treatments
CG = control group EG = experimental group
A) one-shot case study
B) one-group pretest-posttest design
C) posttest-only control group design
D) static group design
E) Pretest-posttest control group design

The symbolization indicated in the question corresponds to the posttest-only control group design, where there are two groups, an experimental group (EG) subjected to the independent variable (X) and a control group (CG) that does not receive the treatment. Both groups are randomly assigned (R). In this design, only the dependent variable is measured after the treatment or exposure to the independent variable, that is, only O2 is observed in both groups. Therefore, the correct choice is C, which corresponds to the posttest-only control group design.
