For Principles of communication systems, which option best supports this approved objective using a clear evidence focus: Compare analogue and digital communication qualitatively?.
- A.Compare analogue and digital communication qualitatively. This answer stays within Principles of communication systems and uses the correct evidence focus.
- B.A vague response that names the topic but does not apply the A-Level Physics reasoning.
- C.A neighbouring-topic response that belongs outside Principles of communication systems.
- D.A response that confuses the quantity, unit, graph feature, evidence, or conclusion required here.
Model answer
What a good answer should say
- The correct option is Compare analogue and digital communication qualitatively.
- This answer stays within Principles of communication systems and uses the correct evidence focus.
Explanation
Why this works
This answer stays within Principles of communication systems and uses the correct evidence focus." because it directly supports the approved learning objective: Compare analogue and digital communication qualitatively. The other options are weaker because they are vague, use the wrong context, or confuse a nearby A-Level Physics quantity, unit, graph feature, evidence point, or conclusion in Electronics.
