Practice question

The right choice is B: SL-deficient mutants. In Striglactone, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) SL-insensitive mutants; C) Auxin mutants; D) GA mutants. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
