Final Answer:
The total cost of fabri-cation with SAW, ESW, and EGW is a) Lower, providing the same or higher service.
Step-by-step explanation:
Sub-merged Arc Wel-ding (SAW), Electro Sl-ag Wel-ding (ESW), and Electro Gas Wel-ding (EGW) are wel-ding processes known for their cost-effective-ness. These methods often offer lower fabrication costs while maintaining or even enhancing the quality of the service provided. The question im-plies that the wel-ding processes are not only eco-nomical but also comparable or superior in service quality.
Therefore, the answer under-scores the cost efficiency of these wel-ding techniques without compromising the standard of service, making them advantageous in various fabrication applications.
"Lower, providing the same or higher service" is the correct answer.
Option A is the answer.
