Explanation:
Detailed explanation-1: -Phelloderm or the secondary cortex is made up of parenchyma or collenchyma cells. Due to the secondary growth of the vascular cambiums, the epidermis bursts. The epidermis is replaced by a protective layer known as the cork or phellem which is formed by the cork cambium or phellogen on the outer side.
Detailed explanation-2: -That means vascular cambium divides to form secondary xylem and phloem and helps in secondary growth and wood formation. So, the correct answer is, ‘(d) Secondary xylem’.
Detailed explanation-3: -Phelloderm or secondary cortex is the thin-walled inner layer of cells produced by cork cambium or phellogen.
