• A. a-Complementary cells, b-Phellogen, c-Phelloderm, d-Periderm
• B. a-Complementary cells, b-Phellem, c-Periderm, d-Phelloderm
• C. a-Phellem, b-Periderm, c-Phellogen, d-Phelloderm
• D. a-Phellem, b-complementary cells, c-Phellogen, d-Phelloderm

Answer 1

The correct option is D a-Phellem, b-complementary cells, c-Phellogen, d-Phelloderm

The large sized slightly raised spots or aerating pores, present in the cork called Lenticels. These are found in old woody dicot stems. They develop from the place of stomata. They perform the gaseous exchange. They have raised margins, with loosely arranged colourless parenchyma cells internally. They are called complementary cells. They may also perform transpiration. Inner to the lenticels, phellogen and phelloderm tissues are also present.

So, the correct option is 'a-phellem, b-complementary cells c.phellogen D-phelloderm'.
