Answer 1

Hint: Pollination is the process of moving pollen grains from a flower's stamen to the ovule-bearing organisms. In flowering plants, the stigma is the part of the pistil where the pollen is deposited and the ovules are located. The pollen tube is created here when the pollen germinates.
Step-by-step solution:

The pollen grains in flowers that are necessary for their reproduction are the source of the term "pollination."
These pollen grains are the male reproductive cells of plants, which are unicellular organisms. These pollen grains are often referred to as plant sperm cells. This occurs when pollen from one plant is transported to the stigma, or female reproductive organ, of another plant.
These reproductive organs are located in the plant's flowers.
A pollen tube known as the style is created when the pollen grains successfully settle on the stigma; this component is a long stalk that is in charge of causing the stigma to merge with the ovary (female part) of the flower.
There are two types of pollination:
1. Self-pollination
2. Cross-pollination
Self-pollination means the transfer of pollen grain to the stigma of the same flower or to the different flower of the same plant. In the second case, it may look cross pollination but genetically it’s self-pollination.
Cross-pollination means the transfer of the pollen grain to the flower of different plants. To carry out, cross-pollination there is a requirement for the agent that helps in carrying the pollen grain from one plant to another. The agents can be broadly divided into two types, abiotic and biotic. Abiotic agents mainly consist of wind, water, etc. The biotic agent consists of insects, animals, etc. There have been certain terms given to different types of biotic agent-mediated pollination.
Zoophily- The practice of using animals to aid in pollination is known as zoophily.
Ornithophily- Pollination with the help of birds.
Entomophily- Pollination with the help of insects.
Chiropterophily- Pollination with the help of bats.

So, option C is correct.
Note: The Asteraceae and Labiatae families of flowers are frequently pollinated by bees and butterflies.
Some wind-pollinated plants, like pinus, have winged pollen grains. The pollen grains are transmitted from the anther to the stigma of the same flower in the case of self-pollinators.
