Solution
The correct option is C Apical shoot meristem
Auxins (from Greek auxein: to grow) was first isolated from human urine. The term auxin is applied to the indole-3-acetic acid (IAA), and to other natural and synthetic compounds having certain growth regulating properties. They are generally produced by the growing apices of the stems and roots, from where they migrate to the regions of their action. Most of the auxins in plants are believed to be produced by apical shoot meristem. This auxin then suppresses the growth of lateral buds, the phenomenon is called as apical dominance. Auxins like IAA and indole butyric acid (IBA) have been isolated from plants. Thus, the correct answer is option C.
