spores are light & small & encapsulated
The spores are very resistant to the the external environment since they are encapsulated structures , this type of dispersal helps past against natural calamities and promotes more living of the plant in further generations in extreme conditions . Since they are light weight and have small size they can be dispersed easily so helps in diversification of the plant in the area . These advantages are not well suited for sperms. Moreover, in mosses, the sperm requires water for the movement to meet the ova cells to make zygote.

The correct answer is option A
The pizza on the Jupiter has the least mass as the weight of the pizza is same,it will have the least mass in the planet with the highest gravity and Jupiter has the highest gravity.
Explanation:
The Moon's gravity is much less than the Earth's gravity. It is approximately one-sixth of the Earth's. The Jupiter gravity is much more intense than Earth's. It is approx 2.528 times more.
Hence, it is the Jupiter where the pizza will have least mass.
