The expression which determines that x is less than or equal to y is option c) x <= y
We know that '<' means 'less than' and '=' means 'equals to'. Also, we can determine the x is less than y by the expression x < y and we can determine x is equal to y by expression x = y. And when both <, = comes together we can say that x is less than or equal to y which mean the value of x is either less than the value of y or value of x is equal to the value of y.
So, in the above question Option C) (x ≤ y) is the correct option be clearly tells the relation between X and Y in such a way that X is less than or equal to Y.
