During Freefall, what is the weight of a body? Give reason for your answer.

Weight can be defined as the force of gravity acting on a mass ..
Weight during freefall is the same as if stationary .. gravity hasn't ceased or changed in strength so there's the same force of gravity still acting on your mass, giving you weight and causing the acceleration.
It may appear to a free-falling person that they are weightless .. but it's artificial. The problem is that conventional forms of weighing will read zero .. because the equipment will be free-falling too (we have to rely on Newton law 2 .. F =ma)

Free fall is any motion of a body where its weight is the only force acting upon it. These conditions produce an inertial trajectory so long as gravity remains the only force. Since this definition does not specify velocity, it also applies to objects initially moving upward. Since free fall in the absence of forces other than gravity produces weightlessness or "zero-g," sometimes any condition of weightlessness due to inertial motion is referred to as free-fall. This may also apply to weightlessness produced because the body is far from a gravitating body.

during freefall and the weight during at rest will be same as the acceleration due to gravity does not change

When a body sets in motion inside a fluid(like atmosphere, water) the viscous force of the fluid which retards its own motion starts retarding the motion of the body until all the force the body exerts on the fluid(like gravitational force) becomes zero so the body moves with a constant velocity called terminal velocity.It is commonly applied to falling under gravity but then it is not called"free fall under gravity" because the body does not accelerate under gravity.

When the objects falls freely means Neglecting the air resistance(all the types of drags associated with the body)then free fall is defined. Weight is the attractive force exerted by the body towards the earth surface. So,weight (W)=mg Here g remains constant. g=9.8m/s^2
