The correct answer is Option (3) – a-4,b-3,c-2,d-1
| Column I | Column II |
| a- Cleistogamous flower | 4- Commelina |
| b- Tallest flower | 3- Amorphophallus |
| c- Fresh water angiosperm | 2- Vallisneria |
| d- Multicarpellary apocarpous pistil | 1-Michelia |
a- Cleistogamous flower (4- Commelina): Cleistogamous flowers are those that self-pollinate without opening. Some plants such as Viola (common pansy), Oxalis, and Commelina produce two types of flowers – chasmogamous flowers which are similar to flowers of other species with exposed anthers and stigma, and cleistogamous flowers which do not open at all.
b- Tallest flower (3- Amorphophallus): Certain plant species offer floral rewards by providing secure locations for egg-laying. One example is the tallest flower of Amorphophallus, which can reach a height of approximately 6 feet.
c- Freshwater angiosperm (2- Vallisneria): Vallisneria is an example of a freshwater angiosperm. It is a genus of aquatic plants commonly known as eelgrass or tapegrass, found in freshwater habitats such as ponds, lakes, and slow-moving rivers.
d- Multicarpellary apocarpous pistil (1- Michelia): Michelia is a genus of flowering plants in the family Magnoliaceae. It is known for having multicarpellary (having multiple carpels) and apocarpous (with free carpels) pistils.
