Practice question

The right choice is A: 12-hydroxy jasmonic acid. In Jasmonic acid, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: B) Methyl jasmonate; C) cis-jasmone; D) JA-Ile. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
