Solution
The correct option is B Salvia
- The flowers in Salvia are arranged in thysrus inflorescence. They are attractive and well adapted for cross-pollination through the agency of insects.
- These flowers show lever mechanism in which the corolla has a spreading upper lip. and a lower lip. These flowers have long bifurcated connectives.
- When the insects land on the lower lip of the corolla to obtain the nectar it pushes the sterile lobes of the stamen inwards.
- Hence the anther lobes come down and shed the pollen on the back of the insect. This results in its pollination.
Thus the correct answer is option A.
