• B. $a,b$ and $d$
  
• C. $b$ and $d$
  
• D. $b,c$ and $d$
  
• E. $b$ and $e$
  

Answer 1

The correct option is C $b$ and $d$


$Vallisneria$ and $Zostera$
$Zostera$ and $Vallisneria$ are water pollinated plants.
$\bullet$In submerged freshwater plants, the pistillate flowers have long stalks while the staminate flowers float on the water surface.
$\bullet$The pollens released is lighter than water and therefore float on the water surface. The pollen flows along with the water current and reaches the stigma of the female flower.
$\bullet$Pollination is completed on the surface of water.
$Amorphophallus$ and $Yucca$
$Amorphophallus$ and $Yucca$ are insect pollinated plants. Both these plants provide the insects a safe place to lay eggs as a reward to facilitate pollination.
Water lily and water hyacinth
Aquatic plants like water lilies and water hyacinth have flowers that emerge out and occupy the surface of the water. Hence, the flowers are pollinated by insects or wind.
