Which of the following is a non-electronic processor mentioned in the material?

• A. Appendix B
• B. Nomograms
• C. Both Appendix B and Nomograms
• D. Manual charts

Answer: (C)

Non-electronic processors are tools that turn input data into calculated results without using electricity or digital devices. Nomograms fit this because they are graphical calculators: you align scales with a straightedge or ruler to read off a result directly from the chart, no power needed. Appendix B in the material is described as a set of hand-calculation methods and charts that produce values by working through steps without electronic tools, so it also acts as a non-electronic processor. Manual charts, while also non-electronic, are more like reference displays rather than active processors, so they aren’t counted the same way in this context. Putting those ideas together, both Appendix B and Nomograms are the non-electronic processors mentioned.
