The answer is A. The program prints:
rocketrocketrocketrocket
This answer was checked by running the program for real.
Why?
Multiplying a string by a number repeats it. * 4 makes 4 copies, joined together with nothing in between.
The code again
word = "rocket"
print(word * 4)
Try it: change one number in the program and predict the new output before you run it.
