A naturally produced plant growth stimulant has been found in which plant?

Explanation:
Growth is boosted in plants by internal hormones called plant growth regulators. Alfalfa has been identified as a natural source of growth-promoting substances, especially cytokinins such as zeatin-type compounds. These cytokinins stimulate cell division and shoot development and can help delay aging in treated tissues. That makes alfalfa a well-known example of a plant containing naturally occurring growth stimulants, which is why it’s the best choice among the options. While the other plants also produce hormones, they’re not typically cited as a standout natural source of a growth stimulant in horticultural practice.
