i. The weight of the spacecraft keeps changing.

iv. The mass of the spacecraft remains the same.

Explanation:

The mass of an object is the quantity of matter in the object. The mass of an object is always constant. It is measured in kilograms and a scalar quantity.

The weight of an object is the amount of the gravitational pull on the object.

       Weight = mass of object × force of gravity

It is measured in Newtons and a vector quantity.

This quantity changes with respect to an object's position on the earth's surface due to the gravitational pull. When an object moves further away from the surface of the earth, its weight varies.

When the spacecraft leaves the gravitational influence of the earth, the Sun applies her gravitational pull on it. Thus changing its weight.

Thus the mass of the spacecraft remains the same, and its weight keeps changing.
