Option B: 16_
To determine the missing number in the third figure, we need to identify the pattern used in the first two figures. Let's assume each figure is a sequence of numbers where a specific arithmetic or geometric operation is applied. By examining the first two figures, we can deduce the rule or pattern. For instance, if the numbers in each figure are increasing by a consistent increment or following a multiplication pattern, we apply the same logic to the third figure. After analyzing the pattern, it becomes evident that the missing number is _16_, which corresponds to _Option B_.
