Final Answer :
A
Explanation :
To find the total number of combinations, we multiply the number of levels for each independent variable.
4 (levels of IV1) x 3 (levels of IV2) = 12 possible combinations. Therefore, the correct answer is A) 12.
4 (levels of IV1) x 3 (levels of IV2) = 12 possible combinations. Therefore, the correct answer is A) 12.
