Equivalent Boolean Expressions

Question

Consider the following code segment.

```java
int x; // value not shown
boolean flag = false;
if (x >= 10) {
    if (x <= 50) {
        flag = true;
    }
} else {
    if (x <= 0) {
        flag = true;
    }
}
```

Which of the following statements assigns the same value to a boolean variable `flag2` as the code segment assigns to `flag` for all integer values of `x`?
