Answer

a. Tech A Explanation 1. Evaluate Tech A's statement Overheated oil can damage seals due to thermal degradation, causing seal failure. Tech A is correct. 2. Evaluate Tech B's statement Electric coil failure in a solenoid generally prevents valve actuation, so failure would affect actuation. Tech B is incorrect.
