• C. Corolla $\to$Calyx $\to$Androecium $\to$ Gynoecium
• D. Calyx $\to$ Androecium $\to$Corolla $\to$ Gynoecium

Answer 1

The correct option is B Calyx$\to$ Corolla $\to$Androecium $\to$ Gynoecium

• The whorls of a flower are arranged on a swollen part which is called thalamus/receptacle. The four whorls of the flower from outside to inside are:

Calyx$\to$Corolla$\to$Androecium $\to$Gynoecium

• Calyx is the outermost whorl which are formed by sepals, the small green leaf like structures.
• Corolla is inner to the calyx which is made up of colorful petals.
• Androecium (the male reproducitve part) follows corolla and then androecium (the female reproductive part) is the inner most whorl of the flower.
