I'm not sure, but I think the answer might be E) A compilation error occurs because of a syntax error in the code

I agree with Reyes, the code prints 0 : 1 : pen because of the way the Predicate is implemented

I think the answer is B) 0 : 1 : pen because the code fragment increments i each time it prints

A) 0 : 0 : pen - This seems like the correct answer. The predicate checks if the string contains 'pen' and prints the value of the counter, which starts at 0 and increments for each match.
