I'm not sure about the syntax error, but I think the output should be A) 1 2 3 4 5 6 7 8 9 10 because the code is sorting and merging two arrays into a vector.

I agree with Kiera, the code is missing a semicolon after 'ostream & out'. So, the correct answer should be E) compilation error.

I think the answer is E) compilation error because there seems to be a syntax error in the code.

But the code is sorting and merging arrays, so I think it's E.
