AI Explanation
The correct answer is B) feeler gauge. A feeler gauge is the best tool to determine the backlash in a gear drive, as it allows for precise measurement of the clearance between the gear teeth. Backlash is the amount of play or looseness in the gear system, and it needs to be within the manufacturer's specified limits to ensure proper gear operation and prevent excessive wear. The other options are not as suitable for accurately measuring backlash. Lead wire and lash indicators are not designed for this specific purpose, and a red dye indicator would not provide a quantitative measurement of the backlash.
