C Correct answer
Explanation

In each row, the third number is double the second number (12*2=24, 16*2=32, 20*2=40).

AI explanation

The numbers in each row follow a consistent multiplication pattern where the first column is multiplied by 4 to get the second column, and the first column is multiplied by 8 to get the third column. For the second row, 4 multiplied by 4 is 16, and 4 multiplied by 8 is 32. Applying this same pattern to the third row, we multiply 5 by 8 to find the missing number, which results in 40. The missing number is 40.
