Why are vectors essential for doing physics? There might be more than one correct answer.

a.Vectors are not needed for idealized particles with zero volume, but they are needed whenever an object has volume. Since all real objects have volume, vectors are needed.

b.Even though vectors are purely mathematical constructions (i.e. you will never see a vector in the real world), they add together in exactly the same way that real world phenomena add together.

c.The universe has more than one dimension, therefore if we are to accurately describe how things behave in the universe we must have multidimensional math.

d.Every object in the world literally is a vector, therefore objects can only be described as vectors.

I need help finding this out

Correct option is : (c) The universe has more than one dimension, therefore if we are to accurately describe how things behave in the universe we must have multidimensional math.

Reason :

Volume is a scalar quantity itself and not a vector one. Also, vectors can be useful for cases other than volume ( like, describing the motion of an object having no volume, like light or sound wave ) too. So, volume has nothing to do with a vector. Therefore, option (a) is not correct.

Vectors are not purely mathematical, istead, it is observed in real life phenomena. So, option (b) is not also a correct statement too.

The universe is a three dimensional object. So, to describe a particle or an object precisely, vectors are a useful tool. Hence, option (c) is a correct statement.

Lastly, objects are not vectors, instead, the motions or positions or dimensions etc can be described by a vector. So, option (d) is an incorrect statement.
