The Correct Option is A

Step 1: Characteristics of bird-pollinated flowers.
Bird-pollinated flowers (ornithophilous flowers) exhibit the following traits: Bright colors (e.g., red, orange, yellow) to attract birds. Long, tubular shapes that allow birds to access nectar. No strong fragrance since birds rely on sight, not smell. Step 2: Explanation of options.
Option (A): Correct. Long, tubular, and brightly colored flowers are adapted for bird pollination. Option (B): Incorrect. Strongly fragrant flowers are more likely to attract insects, not birds. Option (C): Incorrect. Flowers that open at night and emit strong scents are adapted for moth pollination. Option (D): Incorrect. Small and inconspicuous flowers rely on wind or water pollination, not birds. \[ \therefore \text{The correct answer is: A flower with a long, tubular shape and bright red color.} \]
