Match Column - I with Column - II and choose the correct answer.

To find the correct match, let us analyze the floral formulas provided in Column - I and relate them to the plant families in Column - II:

(a) $\%⚥K_{\left(5\right)}{C}_{1+2+\left(2\right)}{A}_{\left(9\right)+1}{\underset{\_}{G}}_1$ matches with (iii) Fabaceae:
- $\%$ indicates a zygomorphic (bilaterally symmetrical) flower.
- $⚥$ indicates a bisexual flower.
- $K_{\left(5\right)}$ indicates 5 fused sepals (gamosepalous).
- $C_{1+2+\left(2\right)}$ represents a papilionaceous corolla with 5 petals (1 standard, 2 lateral wings, and 2 fused keel petals).
- $A_{\left(9\right)+1}$ represents diadelphous stamens (9 fused in a bundle and 1 free).
- ${\underset{\_}{G}}_1$ represents a monocarpellary superior ovary.
Therefore, a - (iii).

(b) $\oplus ⚥K_{\left(5\right)}{\stackrel{⌒}{C_{\left(5\right)}A}}_5{\underset{\_}{G}}_2$ matches with (iv) Solanaceae:
- $\oplus$ indicates an actinomorphic (radially symmetrical) flower.
- $K_{\left(5\right)}$ and $C_{\left(5\right)}$ indicate fused sepals and fused petals (gamopetalous) respectively.
- The arc connecting Corolla (C) and Androecium (A) represents epipetalous stamens (stamens attached to the petals).
- ${\underset{\_}{G}}_2$ indicates a bicarpellary, syncarpous, superior ovary.
Therefore, b - (iv).

(c) $\oplus ⚥{\stackrel{⌒}{P_{\left(3+3\right)}A}}_{3+3}{\underset{\_}{G}}_{\left(3\right)}$ matches with (ii) Liliaceae:
- $P_{\left(3+3\right)}$ indicates a perianth composed of 6 tepals arranged in two whorls of 3, which are fused.
- The arc connecting Perianth (P) and Androecium (A) represents epiphyllous stamens (stamens attached to the tepals).
- ${\underset{\_}{G}}_{\left(3\right)}$ indicates a tricarpellary, syncarpous, superior ovary.
Therefore, c - (ii).

(d) $\oplus ⚥K_{2+2}{C}_4{A}_{2+4}{\underset{\_}{G}}_{\left(2\right)}$ matches with (i) Brassicaceae:
- $K_{2+2}$ indicates 4 sepals arranged in two whorls of 2.
- $C_4$ indicates 4 free petals arranged in a cruciform (cross-like) pattern.
- $A_{2+4}$ indicates tetradynamous stamens (6 stamens total: 2 outer short stamens and 4 inner long stamens).
- ${\underset{\_}{G}}_{\left(2\right)}$ indicates a bicarpellary, syncarpous, superior ovary.
Therefore, d - (i).

Combining all the matched pairs, we get:
a - (iii), b - (iv), c - (ii), d - (i)
