Answer:
A. How much matter an object has, plus the magnitude and direction of its motion
Explanation:
Momentum is defined as the product of mass by velocity, in the international system of measurements (SI) momentum has the following Units [kg*m/s].
P = m*v
where:
P = momentum Lineal [kg*m/s]
m = mass [kg]
v = velocity [m/s]
Therefore the answer is A) How much matter an object has, plus the magnitude and direction of its motion
If a body is moving from left to right or right to left it is linear motion in x- direction. It is also called one dimensional motion.
If a body is moving up to down or down to up it is linear motion in y- direction. It is also called one dimensional motion.
But if a body is moving forward as well as downward it travels in X direction and in y direction at the same time. Such a motion is called two dimensional motion.
E.g motion of a ball.
Attachment shows path of two dimensional motion of a ball.

You can conclude that the force of static friction acting on the boxcar is equal to 200N while you're pushing on it.
