The answer is B. The program prints:
gadget gadget gadget gadget

Why?
Multiplying a string by a number repeats it. * 4 makes 4 copies, joined together with nothing in between (the ‘ ‘ is part of each copy).
The code again
word = "gadget"
print((word + " ") * 4)
Try it: change one number in the program and predict the new output before you run it.
