Review the negative-number check

An AI generated this function to report whether a list contains any negative number. It passes every test you try. Which review comment is the most justified?

def contains_negative(numbers):
    found = False
    for n in numbers:
        if n < 0:
            found = True
    return found

Choose one

It is incorrect: it returns True for an empty list It is correct, but it keeps looping after finding a negative; returning True immediately would be clearer and faster It must be rewritten with a while loop, because for loops are unsafe with lists No change is ever worth making to code that passes its tests

Why this activity was chosen

Bloom level: L6 Evaluation: Judge working code and pick the most justified review comment.
Block Model level: Macro Structure (step 4 of 4): the purpose of the whole program: the problem it solves and the goal it serves.
Misconception targeted: shown after you answer, so it does not give the answer away.

Evaluating quality is different from checking correctness. Learners practise separating 'wrong' from 'could be better', and rejecting confident but unjustified criticism or praise, which is a core skill when reviewing generated code.

AI’s role here: AI may prompt the learner to test correctness first. It must not rank the comments.
