The correct answer is:
c. Both A and B
Explanation:
1. Technician A is correct because there is a concern of damaging lower strength steels when straightening High-Strength Steel (HSS). HSS requires specialized techniques and equipment to prevent damage to other components during the straightening process.
2. Technician B is also correct because when straightening a multi-layered pillar, there is a risk of causing spot welds to break. The application of force and heat during the straightening process can weaken or break the spot welds holding the layers of the pillar together.
