Short Answer
Bosons have symmetric wavefunctions and fermions antisymmetric is the best answer.
Quantum questions reward precision with language. Identify whether the prompt is about wave behaviour, measurement, states, operators, or quantised energy levels before choosing a formula or interpretation.
Integer-spin particles (bosons) have symmetric wavefunctions; half-integer-spin particles (fermions) have antisymmetric ones.
Why This Answer Is Correct
This is a Medium-level question in Quantum Physics. The prompt is really testing whether you can connect the concept to its defining physical relationship instead of picking a nearby-but-wrong term.
When a quantum question feels ambiguous, translating it into state, observable, probability, and evolution language usually clarifies the answer.
Choices At A Glance
- A. Bosons obey Fermi–Dirac statistics
- B. Particles with integer spin are fermions
- C. Particles with half-integer spin obey Bose–Einstein statistics
- D. Bosons have symmetric wavefunctions and fermions antisymmetric
When similar options appear on an exam, eliminate the ones that break the core law, use the wrong units, or confuse a definition with a consequence.
