Which of the listed statements is correct when using a digital multimeter set up as an ohmmeter?

AWith the test leads shorted together, a reading of 'OL' ohms will be displayed.
BWith the test leads apart insulated from each other, a reading of 'zero' ohms will be displayed.
CIt is usually not possible for a digital multimeter to be set up as an ohmmeter.
DWith the test leads shorted together, a reading of 'zero' ohms will be displayed.
AI Explanation

The correct answer is D) With the test leads shorted together, a reading of 'zero' ohms will be displayed. When using a digital multimeter set up as an ohmmeter, shorting the test leads together will result in a reading of zero ohms, as this indicates a direct connection with no resistance between the leads. This is the expected and correct behavior for an ohmmeter function. The other options are incorrect: A) 'OL' (overload) would indicate an open circuit, not a short circuit. B) A reading of zero ohms would not be displayed with the leads apart, as that would indicate an infinite resistance. C) Digital multimeters can be readily set up to function as ohmmeters, measuring resistance between the test leads.
