Answer:
A. Harry no longer has 20/20 vision, which is required to safely drive the trucks.
Explanation:
VF Delivery Service will prevail if it can show that Harry no longer has 20/20 vision, which is required to safely drive the trucks.
This is because the Vision 20/20 is the standard on an optician chart for drivers and this indicates that drivers can see clearly from a distance of 20 feet.
Since Harry is 60 years of age, if he is made to undergo an optical eye test by the VF delivery service, his score would not match the vision 20/20 which would mean or indicate that Harry is unfit to be a driver due to his poor eyesight which was why they terminated his contract and this would allow the VF Delivery Service to prevail and dismiss Harry's case which is on the basis or grounds of age discrimination.
