D it is.. I have tested it

The answer is D. if you run this code to decorator a new function, you will get name error, regardless the colon in line 3 is missing or not. NameError: name 'level2_warpper' is not defined. This is because our_function (line 4) and my_function(line 2) did not return the SAME function name. line 2: def level1_wrapper(my_function) line4: return our_function To make this code correct, you can make FUNCTION_NAME in line 2 and line 4 consistency. eg. line 4 should be ' return my_function' B is Wrong. Because we did not have two more decorators for decorator stacking. C is Wrong. Because the decorator returns arguments 2 times (2 level wrap), not infinite recursion. A is NOT the answer since the code is wrong. A could be a correct answer if the code is consistency. my_func('smallcoat','middlecoat')

Selected answer c

Not only the wrapper is missing the colon, it's calling own_function, which wasn't defined anywhere
