Space is the region of the universe outer to the planet. If anyone is sent to space then their mass remains the same but weight changes.
Weight includes the mass and the gravitational acceleration. It gets altered in space because the gravity differs at space and planets and hence the weight being dependent on gravity will be changed in space.
Mass is the product of the density and volume of the object occupied in a specified place. The mass of the object does not depend on gravity and hence does not get altered in space.
Therefore, the correct blanks are option D. mass and weight.
