Which оf the оptiоns provided аre legitimаte reаsons for using a static variable instead of a non-static variable in a class? I. The variable refers to a constant that can be used in other classesII. The variable refers to one value that is the same across all instances of the class it is defined inIII. The variable refers to an important piece of information unique to each new object created from this classIV. The variable refers to a count of the number of times a new object from this class is constructed
