The correct option is B lacks vessels
Hardwoods or Angiosperms have a more complex structure. The main feature separating them from Softwoods or Gymnosperms are the water-conducting cells, vessels or pores and tracheids, plus more or less thick-walled and tightly-packed wood fiber cells, lacking in softwoods. Softwoods are composed essentially of water-conducting cells in the form of tracheids and medullary rays.
