Answer:
The correct option is;
Technician A
Step-by-step explanation:
Here we note failure analysis will assist in determining the cause of failure and as such to determine the cost effectiveness of a repair or a replacement.
However, a warranty is a legal contract between the buyer of the engine and the manufacturer for the manufacturer to either repair the engine or compensate the the customer for all failures that occur within the period of the warranty. Therefore, technician B is not correct as he says the manufacturer may request the engine for analysis on why it failed which is not the same as the basis of a warranty.
