Answer 1

Hint: Pollination is a process in which pollen grain transfers from the anther to the stigma of pistil by an agent. This agent could be wind, water, birds, insects etc. Pollination is two of type self pollination and cross pollination.

Complete answer:
In the Pisum sativum plant, self pollination is found. In this type of pollination, pollen grains are transferred to the stigma of the same flower or the stigma of the different flowers of the same plant.

In Commelina plant chasmogamy and cleistogamy type of pollinations are found. Chasmogamy is the simple type of cross pollination, where pollination takes place in open flowers. Cleistogamous pollination takes place between the simple, bisexual, colourless flowers, which do not secrete nectar and always remain close.

When the pollen grains are transferred by an agent which is specifically insects such a type of pollination is known as entomophily or insect pollination. Pollination done by the wind is called anemophily. Water hyacinth is an aquatic plant, and this plant has emergent flowers, in which pollination is done by wind and insects.

Protogyny is the condition, in which development and maturation of female reproductive parts of flower have done earlier of male parts of flower due this self pollination prevented in this condition. This phenomenon is found in Abutilon plants, and this plant exhibits entomophily pollination.
In solanum cross pollination is found and self pollination is restricted due to this, this plant is self sterile.

Hence, the correct answer is option (A).

Note: About 75% of all angiosperm plants species depend on animals to initiate the process of fertilization, because animals (E.g.; insects and birds) are able to move their heavy pollen grains from plant to plant.
