Answer
# Brief Explanations:
The reduction ratio in gears is indeed the ratio of the number of teeth of the driving gear to the driven - gear. Also, it is inversely related to the ratio of the rotational speeds (the driving gear has a lower rotational speed relative to the driven gear when there is a reduction). So the statement is correct.
# Answer:
A. True
