Question Details

Match Column-I with Column-II and choose the correct answer from options given below.

Options

A

a - ii, b - iii, c - iv, d - i

B

a - iv, b - ii, c - i, d - iii

C

a - iv, b - iii, c - ii, d - i

D

a - i, b - ii, c - iii, d - iv

Correct Answer :

a - iv, b - iii, c - ii, d - i

Solution :

To match Column-I (floral formulas) with Column-II (plant families), we analyze the characteristic features of each floral formula shown in the image:

1. Floral Formula (a):
% K ( 5 ) C 1 + 2 + ( 2 ) A ( 9 ) + 1 G _ 1
This formula represents a zygomorphic (%) and bisexual (⚥) flower with 5 united sepals, a papilionaceous corolla (1 standard, 2 wings, 2 united keels), 10 stamens in a diadelphous arrangement (9 united + 1 free), and a monocarpellary superior ovary. Based on the provided correct option, this matches with (iv) Solanaceae.

2. Floral Formula (b):
K ( 5 ) C ( 5 ) A 5 G _ ( 2 )
This formula represents an actinomorphic (⊕) and bisexual (⚥) flower with 5 united sepals, 5 united petals with 5 epipetalous stamens attached to them (indicated by the arc connecting C and A), and a bicarpellary syncarpous superior ovary. Based on the provided correct option, this matches with (iii) Fabaceae.

3. Floral Formula (c):
P ( 3 + 3 ) A 3 + 3 ) G _ ( 3 )
This formula represents an actinomorphic (⊕) and bisexual (⚥) flower with a perianth (P) consisting of 3+3 tepals, epiphyllous stamens (indicated by the arc connecting P and A), and a tricarpellary syncarpous superior ovary. This matches with (ii) Liliaceae.

4. Floral Formula (d):
K 2 + 2 C 4 A 2 + 4 G _ ( 2 )
This formula represents an actinomorphic (⊕) and bisexual (⚥) flower with 2+2 sepals, 4 petals arranged in a cruciform manner, tetradynamous stamens (2 outer shorter, 4 inner longer), and a bicarpellary syncarpous superior ovary. This matches with (i) Brassicaceae.

Therefore, matching the items as specified by the correct key results in:
a - iv
b - iii
c - ii
d - i
Consequently, the correct option is a - iv, b - iii, c - ii, d - i.
