Final answer:
In automotive technology, starters are classified based on the type of pinion gear engagement.OPTION A.
Step-by-step explanation:
In the field of automotive technology, starters are classified based on the type of pinion gear engagement, so Tech A is correct. The pinion gear is a part of the starter motor that engages with the engine's flywheel to start the engine. There are two common types of pinion gear engagement: the Bendix drive and the inertia drive.
Tech B is incorrect because starters are not grouped by the type of armature. The armature is the rotating part of the starter motor that uses electrical power to create the rotational movement. Different types of armatures may be used in starters, but they do not determine the classification of starters.
Therefore, the correct answer is A. A only.
