  2. Bvascular bundles are surrounded by sclerenchymatous bundle sheath .
  3. Cthe vascular cylinder is surrounded by a parenchymatous pericycle in monocot stem
  4. Dperipheral vascular bundles are generally larger than the centrally located ones.

Correct answer

B. vascular bundles are surrounded by sclerenchymatous bundle sheath .

Step-by-step solution

The monocot stem has a sclerenchymatous hypodermis, a large number of scattered vascular bundles, each surrounded by a sclerenchymatous bundle sheath, and a large, conspicuous parenchymatous ground tissue. It doesn't have pericycle. Vascular bundles are conjoint and closed. Peripheral vascular bundles are generally smaller than the centrally located ones.
