Solution

The correct option is B Heterochlamydeous, gamopetalous, tetramerous and bisexual
  • The given image describes the flower with the help of a floral formula. Heterochlamydeous is the condition when the two whorls calyx and corolla are differentiated by different structures and colors.
  • Gamopetalous is the condition in which the petals in the flower are fused to form a united structure.
  • The corolla may look like a tube or funnel. There are four petals and four sepals.
  • This denotes the tetramerous condition where the tetra means four. The male and female reproductive organs are shown in the diagram in the same flower. This describes the bisexual condition in which both the sexes are present in the same flower.
Thus, the correct answer is option B.
