Answer 1

Answer: (A)

Option (a) is the incorrect match and can be corrected as
Vessels are cells with lignified cell wall. Mature vessels are dead and without nucleus.
These long cylindrical tube-like structures made up of many cells called vessel members and a large central cavity. The vessel cells are also devoid of protoplasm. Vessel members are interconnected through perforations in their common walls.
