A. An object that's thrown horizontally off a cliff and allowed to fall

B. An object thrown upward at an angle

Explanation:

An object exhibits a two-dimensional motion if it can be described by both x and y coordinate components.This means you can describe it using a vector with the horizontal and vertical components.For example,a graph of a body that moves with a constant velocity,the sum of the velocities in the x and y directions can describe this object's position.The same with kicking a ball.The ball will rise up at an angle, where you will have the horizontal component in the x-axis direction and the vertical component in the y-axis direction.

So for the case of this question, when an object is thrown horizontally, the horizontal component is initiated which will be represented by the x-axis vector.When it is allowed to fall down, the vertical component is initiated, in this case it will be a negative vector.An object thrown upward at an angle behaves like a ball kicked at an angle.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
