Alead wire
Bred dye indicator
Cfeeler gauge
Dlash indicator
AI Explanation
The correct answer is C) feeler gauge. A feeler gauge is the best tool to determine the backlash in a gear drive. Backlash is the amount of clearance or play between the mating gear teeth, and a feeler gauge can precisely measure this clearance. Using a feeler gauge allows you to insert the appropriate thickness of the gauge between the gear teeth and accurately assess the amount of backlash present. The other options are not as suitable for measuring backlash. A lead wire or dye indicator would not provide a precise measurement, and a lash indicator is typically used to measure the wear or looseness in a mechanical linkage, not a gear drive.
