Answer 1

Hint: Reproduction also referred to as breeding is the biological process by which new individuals that are termed as offspring– are produced from their parents. The process of reproduction is a fundamental feature of every living organism. The reason for the existence of every organism is due to reproduction. It is divided into two forms: asexual and sexual.

Complete answer:
There are two types of reproduction-
• Asexual reproduction involves the reproduction in which an organism can reproduce without the involvement of another organism.
• It is confined to only single-celled organisms.
• The formation of colonies of an organism is an example of asexual reproduction.
• As a result, an organism creates a genetically similar copy.
• In sexual reproduction, it is estimated that only 50% of organisms reproduce and pass half of this to the remaining generation.
• It requires the sexual interaction of two concerning factors, called gametes, which contain half the number of chromosomes of normal cells (n) and are created by meiosis.
• A male fertilizes a female of the same species to create a fertilized zygote. This produces offspring or future generations whose genes are derived from those of the parental organisms involved in reproduction.

Hence, the correct answer is option (C).

Note: Energy requirements of an organism are met by intake of a balanced diet and ATP is required or utilized for energy. The organ of an organism develops from stem cells and it is not concerned with reproduction. As long as an organism is healthy, the organs remain healthy.
