David Silva · Accepted Answer

Final Answer : C, Explanation :  The geometric mean of two numbers is the square root of their product. Thus, the geometric mean of 8 and 12 is the square root of 8 times 12, which is the square root of 96. Simplifying the square root of 96, it becomes 4 times the square root of 6. Therefore, the correct answer is C, which is  .
