(D) In a dicot stem,secondary growth occurs in two regions: the stelar region and the extra-stelar region.$1$. The stelar secondary growth is caused by the vascular cambium (formed by intrafascicular and interfascicular cambium).$2$. The extra-stelar secondary growth (also known as cork formation or periderm formation) is responsible for replacing the epidermis and cortex as the stem increases in girth.$3$. This process is initiated by the $Phellogen$ (cork cambium),which is a meristematic tissue that develops in the cortex region.$4$. Therefore,$Phellogen$ is responsible for the extra-stelar secondary growth.

Which of the following meristems is responsible for the formation of the extra-stelar secondary growth in a dicot stem?
