What is the output of the given code segment when executed?

The output of the code segment being 'i = 30, i = 30' indicates that at the point where the code runs, the variable 'i' has been assigned the value of 30 twice. This often occurs in scenarios where the variable is set through either assignments or function calls that explicitly modify its value.

If the code includes operations that change 'i' to 30, followed by another operation that does not alter its value again, we end up with the same final output of 30 for both instances where it is printed or assigned. This implies that initial changes made to ‘i’ effectively persist, leading to repeated assignments resulting in the same output.

In programming, consistently assigning the same value to a variable multiple times does not change the value—it remains constant as long as no further operations legitimately modify it in between. In this case, it reinforces the state of 'i' through those operations, making the output logical and consistent.

This matches the output found in choice C.
