A function from A to B is called the onto function if its range is?

Explanation
  • A function f from A to B is called an onto function (or surjective function) if its range is equal to the codomain B.
  • In other words, every element in B is the image of at least one element in A.
  • This means that the function covers all the elements in the codomain B, and no element in B is left out.
  • So, the correct answer is B.
