Inertia is defined as the property of matter by which causes it to resist changes in its state of motion such as changes in velocity. From the given options above, the option that has the greatest inertia would be option B. A jet airliner.

Explanation:
Answer is B.
In a lever, the effort arm is 2 times as a long as the load arm. The resultant force will be twice the applied force.
Hope it helped you.

Answer:
Newton, absolute unit of force in the International System of Units (SI units), abbreviated N. It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second.
Let both the balls have the same mass equals to m.
Let
and
be the speed of the ball1 and the ball2 respectively, such that
![v_1>v_2\;\cdots(i)](https://tex.z-dn.net/?f=v_1%3Ev_2%5C%3B%5Ccdots%28i%29)
Assuming that both the balls are at the same level with respect to the ground, so let h be the height from the ground.
The total energy of ball1= Kinetic energy of ball1 + Potential energy of ball1. The Kinetic energy of any object moving with speed,
, is ![\frac 12 m v^2](https://tex.z-dn.net/?f=%5Cfrac%2012%20m%20v%5E2)
and the potential energy is due to the change in height is
[where
is the acceleration due to gravity]
So, the total energy of ball1,
![=\frac 12 m v_1^2 + mgh\;\cdots(ii)](https://tex.z-dn.net/?f=%3D%5Cfrac%2012%20m%20v_1%5E2%20%2B%20mgh%5C%3B%5Ccdots%28ii%29)
and the total energy of ball1,
.
Here, the potential energy for both the balls are the same, but the kinetic energy of the ball1 is higher the ball2 as the ball1 have the higher speed, refer equation (i)
So, ![\frac 12 m v_1^2 >\frac 12 m v_2^2](https://tex.z-dn.net/?f=%5Cfrac%2012%20m%20v_1%5E2%20%3E%5Cfrac%2012%20m%20v_2%5E2)
Now, from equations (ii) and (iii)
The total energy of ball1 hi higher than the total energy of ball2.
