• The ovary ripens to form fruit while the ovule ripens to form a seed after fertilization. Thus, the first statement is False.
• Seeds of the fruits get dispersed by different methods. 
• The coconut plant produces the fruit with a fibrous coating that allows the fruit to float in the water. The seeds of the fruits in coconut are dispersed with the help of water. So, the second statement is True.
  
• Pollination is the transfer of pollen from stamen to the stigma of the same flower or different flower of the same species before fertilization. Hence, the third statement is True.
• Cutting, layering, grafting, and tissue culture are artificial methods of vegetative propagation. So, the fourth statement is False.

• Breast development is the secondary sexual characteristic in females which occurs during puberty due to the hormones like estrogen and progesterone. 
• Secretion of these hormones starts at puberty and thus contributes to the appearance of secondary sexual characteristics at this age.
• So, the correct answer is option A.

• If the individual is cut or broken up into many pieces accidentally, these pieces can regrow into separate individuals. This is called regeneration.
  
• Some species, like Hydra and Planaria, undergo regeneration. 
• Budding occurs in Saccharomyces (yeast).

• Oral contraceptives are commonly known as 'the pill', or 'birth control pill'.
• Most birth control pills contain a combination of the hormones estrogen and progestin, which is why they are also called 'combined pills' or 'combination pills'.
  
• The pill works mainly by changing the body's hormone balance so that the woman does not ovulate. 
• It is more effective if taken correctly and consistently.

• The process by which thousands of plants can be raised within a limited time and space is Tissue culture.
  
• The process of growing new plants from a small piece of plant tissue or cells removed from the growing tips of a plant in a suitable growth medium, is called tissue culture.
  
• Its advantages are:

$$\textbf{Correct Option A}$$

$$\textbf{Solution}$$

$$\bullet$$ Use of condom is the most effective way in order to inform birth control as well as preventing AIDS.

1. Paramecium: It undergoes fission, a type of asexual reproduction. It duplicates all the contents of the cell and divides into two halves generating two daughter cells.
2. Spirogyra: It reproduces by the process of fragmentation. The organism splits into small fragments and each fragment produces a new Spirogyra.
3. Planaria: It can regenerate any lost part of its body. It undergoes asexual reproduction by regeneration.
4. Mucor: It reproduces by spore formation. It produces spores that can germinate and form an individual organism. 

• Gametes are the special lineages of cells in reproductive organs in which only half the number of chromosomes and half the amount of DNA is present, as compared to the non-reproductive body cells.
  
• Gametes are of two types: male gamete (sperm) and female gamete (egg cell).
