The correct option is (b) Adventitious roots arise from all parts of the plant

except for the stem.

Explanation:

• The correct statement is Adventitious roots arise from all parts of the plant except for the root.
• Adventitious roots are plant roots that sprout from any non-root tissue and are formed both during normal development (crown roots on cereals and nodal roots on strawberries and in reaction to stressful circumstances, like flooding, nutrient scarcity, and injury.
• They are crucial for human existence, the environment (environmental stress response), and the economy (for cuttings and food production) (food production).
• Understanding the adventitious root formation of crops under both normal and stressful settings is crucial for enhancing sustainable food production in harsh environmental situations.
