The correct answer to the question is D. the Impulse which I.and the extent of the mass and velocity is called momentum.EXPLANATION:The momentum of a body is defined as the amount of movement contained in the body.Quantitatively the momentum of a body is the product of mass with the velocity of the body.Mathematically it can be written as the momentum P = m × vHere, m is the mass of the body and v is the velocity of the body.The inertia of a body is defined as the property by virtue of which a body at rest will be at rest or a body in motion with a uniform speed stays in motion with the same speed.Quantitatively, the inertia is simply the measure of the mass of the body.The acceleration of a body is the rate of change of the speed. So, it may not be a measure of the mass and the velocity of a body.In the same way that gravity can not be considered as the measure of the mass and the speed. This is so because it is the force with which any body on the surface of the earth is attracted towards the center of the earth.Therefore, the correct answer will be the impetus.
