B. Tracheids	(ii) Single layer
C. Stomata	(iii) Cork
D. Epidermis	(iv) Tubular dead cells

• A. A-(iii), B-(iv), C-(i), D-(ii)
• B. A-(i), B-(ii), C-(iii), D-(iv)
• C. A-(iii), B-(ii), C-(iv), D-(i)
• D. A-(iii), B-(ii), C-(i), D-(iv)

Answer 1

The correct option is A A-(iii), B-(iv), C-(i), D-(ii)

A. Secondary meristem in the cortex forms the cork. Cork is made up of compactly arranged dead cells. It contains the waterproof substance suberin.

B. Tracheids are thick-walled tubular structures. They become dead as they mature. They play an important role in the transport of water and minerals vertically in plants.

C. Stomata are small pores found in the epidermis of the leaf. They are bound by two kidney-shaped guard cells.

D. Epidermis is the outermost layer of cells. It is mostly single-layered in all plants but in special cases, it can be more than one like in desert plants.

So, the correct option is A.
