Question 134 pts

Which one of the following statements is true about using arrays with methods?

A method can only accept arguments that are elements of an array, but not the whole array.

A method may accept an argument that is an array, but it cannot return a result that is an array.

Arrays can be method arguments, and return values, just like any other values.

If a method is defined to have an array as a method argument, it must also define the size of the array as another method argument.
