Answer : The correct option is, (B) 1, 4, and 6
Explanation :
Boyle's Law : It is defined as the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles. In this volume of gas changes.
Charles' Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles. In this volume of gas changes.
Gay-Lussac's Law : It is defined as the pressure is directly proportional to the temperature of the gas at constant volume and number of moles. In this volume of gas is constant.
Therefore, the volume should be placed in cell numbered 1, 4, and 6.

The first: alright, first: you draw the person in the elevator, then draw a red arrow, pointing downwards, beginning from his center of mass. This arrow is representing the gravitational force, Fg.
You can always calculate this right away, if you know his mass, by multiplying his weight in kg by the gravitational constant
let's do it for this case:
the unit of your fg will be in Newton [N]
so, first step solved, Fg is 637.65N
Fg is a field force by the way, and at the same time, the elevator is pushing up on him with 637.65N, so you draw another arrow pointing upwards, ending at the tip of the downwards arrow.
now let's calculate the force of the elevator
so you draw another arrow which is pointing downwards on him, because the elevator is accelating him upwards, making him heavier
the elevator force in this case is a contact force, because it only comes to existence while the two are touching, while Fg is the same everywhere
