Answer:

option A

Explanation:

given,

Length of boat = 4 m

width of boat = 2 m

height up to which water is displaced = 1 m

Volume of water displaced by the boat

 V =  L x B x H

 V = 4 x 2 x 1

 V = 8 m³

buoyant force acting on the boat

F_b = ρ g V

m g = ρ g V

 m = ρ V

ρ is the density of water which is equal to 1000 Kg/m³

 m = ρ V

 m =1000 x 8

 m = 8000 Kg

hence, mass of the boat is equal to 8000 Kg

so, the correct answer is option A

<h3>What is a Parachute?</h3>

This is a device used to slow the motion of an object through an atmosphere by creating drag.

The size of the parachute affects the speed of falling because a larger parachute allows it to displace more air, causing it to fall more slowly. The one with three parachutes which is A will fall slowest and the one with just one will fall fastest.
