• A. To attract human
• B. To attract polinators
• C. To remain fragrant longer
• D. To prevent fading of colour

Answer 1

The correct option is B

To attract polinators

Pollination is an example of mutualism, i.e., a system in which plants and pollinators both benefit from each other. Most of the pollinators are bees, butterflies, moths and other insects. Fragrance and colours aid in attracting insects. In the dark, due to limited vision, white colour will stand out and the strong fragrance also helps to attract the pollinators. This is why night blooming flowers have relatively more fragrance and is generally white in colour.
