Explanation:

The function button on a multimeter is often used to change the meter from auto - ranging (where the meter automatically selects the appropriate measurement range) to manual - ranging (where the user selects the range). This is a common function of the button. Increasing the rotary dial capabilities is not its main function. Toggling between AC and DC is usually done via the rotary dial or specific AC/DC buttons, not just the function button in most cases.

Answer:

A. change the meter from auto to manual ranging
