Jupiter is significantly larger than Mercury. In fact, Jupiter is about 40 times the diameter of Mercury. Therefore, if the scale is accurate, the size of Jupiter would not be accurately represented by any of the options listed. However, if we were to select the closest approximation based on the choices provided, Jupiter would be more than ten times the size of Mercury.
Given the options, none accurately represent the true scale, but the answer that aligns most closely with the fact that Jupiter is much larger is likely intended to be "It will be ten times the size," though the actual ratio is much higher.
