Explanation:

Ornithophily or bird pollination is the pollination of flowering plants by birds. This sometimes (but not always) coevolutionary association is derived from insect pollination (entomophily) and is particularly well developed in some parts of the world, especially in the tropics, Southern Africa, and on some island chains.[1] The association involves several distinctive plant adaptations forming a "pollination syndrome". The plants typically have colourful, often red, flowers with long tubular structures holding ample nectar and orientations of the stamen and stigma that ensure contact with the pollinator. Birds involved in ornithophily tend to be specialist nectarivores with brushy tongues and long bills, that are either capable of hovering flight or light enough to perch on the flower structures.

Answer 2

Answer:

Ornithophily is pollination by birds, characteristic is presence of colored flowers ( mostly red) with nectaries. The orientation of the stigma and anthers is to facilitate pollen transfer for cross pollination.

So, the correct answer is 'Yellow flower with nectaries at the base of the corolla tube'
