Which of the following floral formula is the correct floral formula...

The Solanaceae family exhibits the following floral characteristics:

- Symmetry: Actinomorphic, represented by $\oplus$.
- Sexuality: Bisexual.
- Calyx: 5 sepals that are united (gamosepalous), represented by $\text{K}_{(5)}$.
- Corolla: 5 petals that are united (gamopetalous), represented by $\text{C}_{(5)}$.
- Androecium: 5 stamens that are epipetalous (attached to the petals). This is represented by an arc connecting the corolla and androecium symbols: $\widehat{\text{C}_{(5)} \text{A}_{5}}$.
- Gynoecium: Bicarpellary, syncarpous, with a superior ovary, represented by $\underline{\text{G}}_{(2)}$.

Comparing these features with the given options, Formula (2) correctly displays all these characteristics. Formula (1) is incorrect as it lacks the arc indicating the epipetalous condition. Formulas (3) and (4) are incorrect because they show free sepals or petals (lacking parentheses).

Answer: Formula (2)
