1. Problem Description

The problem asks us to determine the output of a given flowchart, starting with initial values for variables $a$ and $b$.

2. Solution Steps

- The flowchart starts with $a = 2$ and $b = 10$.

- The first decision is to check if $a > b$. Since $2 > 10$ is false, we proceed to the "No" branch.

- In the "No" branch, we update $b$ to $b - a$. So, $b = 10 - 2 = 8$.

- Then, we display the current value of $b$, which is $8$.

- The flowchart then ends.

3. Final Answer

The output of the flowchart is

8. The correct answer is 4) 8.
