Conversion of OPDA to jasmonic acid occurs in:

Pick C: Peroxisome. Thinking through Jasmonic acid step by step rules out the lookalikes and leaves Peroxisome. Skip these: A) Chloroplast; B) Cytosol; D) Nucleus. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

12-oxo-phytodienoic acid (OPDA) is formed in:

The right choice is B: Chloroplast. 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: A) Cytosol; C) Peroxisome; D) Nucleus. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
