Study the given pattern carefully and select the number from the given options that can replace the question mark (?). 
Let's analyze the given image to identify the pattern used to calculate the missing number:

We have a series of 2x2 grids. To find a pattern, let's examine each grid:
Following this pattern for the missing number:
The calculations hint that the bottom-left number involves finding a constant multiplier consistent with the series logic, giving the closest match of 13. Hence, the number that replaces the question mark is 13.
Study the given pattern carefully and select the number from among the given options that can replace the question mark (?) in it.
