D Correct answer
Explanation

Gene mutation is genetically significant because it's the ultimate source of genetic variation, providing raw material for evolution. Option A is incorrect - first reported by de Vries in Oenothera lamarckiana (1900), but Oenothera is not the first report context. Sorghum chlorophyll mutants exist but are examples, not the defining principle. Gene mutation is distinct from chromosomal aberrations.
