Correct answer: C
The given C++ code will result in a compilation error. In C++, the + operator cannot be used directly with char arrays (C-style strings) for concatenation. The expression s1 + " " + s2 is invalid because the + operator is not defined for char arrays. Instead, string concatenation in C++ requires the use of std::string or functions like strcat(). Since the code attempts to use the + operator on char arrays, it will not compile. Therefore, the correct answer is 'Error / त्रुटि'.
