Answer:
a. has more density and mass
Explanation:
A bowling ball has less volume and high mass as compared to a balloon because the size of bowling ball is less than balloon so its volume is also less and we know that the density has an inverse relationship with volume. If volume decreases, density increases and if volume of an object increases, then the density decreases. So size of balloon is larger than a bowling ball then the bowling ball has more density and greater mass.
