Options

  1. AThe cells of the endodermis are rich in starch grains.
  2. BVascular bundles are conjoint, open, and arranged in a ring.
  3. CPericycle is present on the inner side of the endodermis as semi-lunar patches of sclerenchyma.
  4. DHypodermis consists of a few layers of sclerenchymatous cells just below the epidermis.

Correct answer
