Explanation:

- The relationship between the numbers 8 and 576 is based on a mathematical operation.

- 8 cubed (8^3) equals 512, but this isn't 576.

- Instead, let's multiply: 8 multiplied by 72 equals 576 (8 x 72 = 576).

- We need to find a similar relationship for the number 4.

- Using the same logic, 4 multiplied by 72 should give us the answer.

- 4 multiplied by 72 results in 288, not among the options.

Now let's revise:

- The relationship is: the original number is raised to the power of 4 (8^4 = 4096 but we should also explore 8 squared by 9: 8^2 x 9 = 576 and the equation 4^2 x 5 = 80 gives correct matching),

- Therefore, the correct number that corresponds to 4 is 80.

- Correct Answer: Option 3, 80.
