Exam-style question

Which option best identifies the exact concept boundary for The development of understanding of genetics and evolution, Evidence for evolution: students must explain that the fossil record provides evidence for evolution.
- A.Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Evidence for evolution because students must explain that the fossil record provides evidence for evolution.
- B.Scale confusion: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Evidence for evolution.
- C.Process confusion: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on explain that the fossil record provides evidence for evolution.
- D.Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than The development of understanding of genetics and evolution / Evidence for evolution.
