CIncreases because gravity increases.
DRemains the same because her mass remains the same.

option a. decreases because gravity decreases.

Remebmer that the weight is the product of the mass time gravity.

Mass does not change. Gravity decreases as the distance to the center of the earth decreases.

Answer:

Decrease because gravity decreases.

Explanation:

According to second law of motion, the weight of an object is given by the product of its mass and its acceleration.

i.e. W = m g

g is acceleration due to gravity. Here, g = 10 m/s²

Mass of an object remains constant everywhere while its weight varies. We know that g on the surface is given by :

\(g=\dfrac{GM}{d^2}\)

As distance increases, the value of g decreases. As a result, the weight of an astronaut decreases.

So, the correct option is (a) "Decrease because gravity decreases".
