Use some rule and then find out the right option for the blank cell.

To solve for the blank cell, we need to identify the mathematical rule relating the outer numbers to the inner numbers in the diagram.

Step-by-Step Analysis
Examine the Patterns:

The inner numbers are located in the sections formed by the intersection of the diagonals.

Let's check the relationship between the inner numbers and their two adjacent outer numbers:

Left section: The inner number is 14, and the adjacent outer numbers are 2 and 7. Notice that 2 * 7 = 14.

Top section: The inner number is 63, and the adjacent outer numbers are 7 and 9. Notice that 7 * 9 = 63.

Bottom section: The inner number is 30, and the adjacent outer numbers are 2 and 15. Notice that 2 * 15 = 30.

Apply the Rule to the Missing Section:

The blank section is on the right side. The outer numbers adjacent to this section are 9 and 15.

Applying the identified rule (multiply the two adjacent outer numbers): 9 * 15 = 135.
