AI Explanation
The correct answer is A) the method of manufacture and does affect normal operation. The slight wavy appearance of the tips of reduction gear teeth is a result of the manufacturing process, specifically gear hobbing or gear shaping. This manufacturing method can create a slight waviness or undulation along the tooth profile, which is considered a normal characteristic and does not affect the proper operation of the reduction gears. The waviness is not caused by insufficient lubrication, uneven bearing wear, or high lubricating oil temperatures, which are the other options provided.
