D Pretest–posttest design

Step-by-step explanation:

According to the question, Mr Abed is just designing the game and the purpose is to help the grade 3 students learn their mutiplication table, upon completion of the game design, the students are to use (play) it - all this makes up the pretest stage

The result of the game will then be evaluated by Mr Abed to Know if the game is effective or not, if the students have actually learnt their multiplication table by playing the game, if there is need for modification - all this makes the posttest stage.
