The floral formula [figure] is that of
- soybean
- sunhemp
- tobacco
- tulip
Answer
(3) tobacco
Solution
In the given formula, shows an actinomorphic, bisexual flower; K(5) means five united sepals and C(5) five united petals.
A5 is joined to the corolla by an arc, so the five stamens are epipetalous, and G(2) shows a bicarpellary, syncarpous gynoecium with a superior ovary.
As per NCERT, this is the floral formula of Solanaceae, and tobacco belongs to Solanaceae.
Soybean and sunhemp (Fabaceae) have zygomorphic flowers with diadelphous stamens, and tulip (Liliaceae) has a trimerous perianth, so they do not fit.
∴ The formula is that of tobacco.
