List-I List-II
(A) Eupatorium (I) Soft fibres
(B) Helianthus (II) Lacunar collenchyma
(C) Leucas (III) Hair like stone cells
(D) Cannabis (IV) Angular collenchyma
(V) Lamellar collenchyma
The correct match is

• A. (A)- (IV), (B)- (V), (C)- (I), (D)- (III)
• B. (A)- (V), (B)- (IV), (C)- (II), (D)- (I)
• C. (A)- (I), (B)- (II), (C)- (III), (D)- (IV)
• D. (A)- (V), (B)- (II), (C)- (IV), (D)- (III)

Answer 1

The correct option is B (A)- (V), (B)- (IV), (C)- (II), (D)- (I)

Collenchyma with the thickenings on the tangential walls is called lamellar or plate collenchyma. It is developed in Eupatorium,
Collenchyma with wall thickenings localized in the corners is called angular collenchyma. it is present in Helianthus.
Collenchyma may or may not contain intercellular spaces. if the spaces are present in the angular type of collenchyma, the thickened walls occurs next to the intercellular spaces. collenchyma with such distribution of wall thickening is sometimes called lacunar collenchyma,
Soft fibers are found in the phloem or inner bark of the dicots as in Cannabis.
Thus, the correct answer is option (B).
