The statement "Jasmonic acid is required for both root and shoot development" is not entirely accurate. Jasmonic acid (JA) is a plant hormone primarily associated with defense responses against herbivory, pathogens, and abiotic stresses. While JA does play a role in regulating root development and growth, its role in shoot development is not as significant compared to auxin.

Jasmonic acid is more commonly associated with processes such as leaf senescence, flowering, and fruit ripening. It is also involved in the regulation of plant responses to environmental cues and signals, including stress responses. Hence, the correct answer is option 1.
