Based on the exact code presented the correct answer is B, if you remove the ']' from the code obviously the answer becomes [3,1] BUT the fact is ']' exists in the code so you must select B as the correct answer and nor speculate on 'what if's'

If there is no "]" after the for loop then, C would be the answer. Otherwise, "]" cause the error and answer will be B

Selected Answer: B
B: There's an ']' before 'if' statement so the code is erroneous If that wasn't the case, the [3, 1] would be printed

Syntax Error. There is an unmatched extra bracket. (maybe at typo who knows?) Without it the answer is [3,1]
