Vedclass · Answer

(B) The correct matching is based on the position of the floral parts with respect to the ovary on the thalamus:
$1$. Hypogynous: The gynoecium occupies the highest position,while other floral parts are situated below it. Examples include Mustard,Brinjal,and China rose $(1-A-X)$.
$2$. Epigynous: The margin of the thalamus grows upward,enclosing the ovary completely and getting fused with it. The other parts of the flower arise above the ovary. Examples include Guava and Cucumber $(2-C-Z)$.
$3$. Perigynous: The gynoecium is situated in the center,and other parts of the flower are located at the rim of the thalamus at the same level. Examples include Plum,Peach,and Rose $(3-B-Y)$.
Thus,the correct sequence is $1-A-X, 2-C-Z, 3-B-Y$.

Column $I$	Column $II \&$ Column $III$
$(1)$ Hypogynous	$(A)$ Gynoecium occupies highest position; $(X)$ Mustard,Brinjal,China rose
$(2)$ Epigynous	$(C)$ Margin of thalamus grows upward enclosing ovary completely; $(Z)$ Guava,Cucumber
$(3)$ Perigynous	$(B)$ Gynoecium situated in centre; $(Y)$ Plum,peach,rose
