Answer 1

The correct option is A

Cork cells and secondary cortex

Phellogen is an alternative name for Cork Cambium, which is a meristematic tissue layer found in the hypodermis of the dicot stem. The phellogen grows both outwards and inwards. The cells that cuts outwards are called cork cells and the ones that cut towards the inside are called secondary cortex.
