Match the column.

Column-I	Column-II
(a) Calyx	(i) Ovary
(b) Corolla	(ii) Sepal
(c) Stamen	(iii) Stigma
(d) Carpel	(iv) Petal
	(v) Anther
	(vi) Filament

The correct option is A (a) $\to$ ii; (b) $\to$ iv; (c) $\to$ v, vi; (d) $\to$ i, iii
Sepals are green outermost leaf-like floral organs, also called calyx.
Petals are coloured accessory floral organs, above sepals, also called the corolla.
Stamens are male reproductive organs. Each stamen has a slender stalk called filament and there is a terminal knoblike swelling, called anther.
Carpels are female reproductive organs. Each carpel has a basal swollen ovary, a stalk-like style and a terminal sticky part called stigma.
Thus, the correct answer is option (A), '(a) ii; (b) iv; (c) v, vi; (d) i, iii.'.
