Answer:
C) behavioral isolation
Explanation:
The mechanisms of reproductive isolation that prevent the formation of a zygote by interbreeding between the individuals of two different species are called pre-zygotic isolation mechanisms. Behavioral isolation is one of such pre-zygotic isolation mechanisms. It includes the exchange of specific signals between the individuals of the same species before mating. Such specific courtship behaviors represent behavioral isolation.
Different species of fruit flies exhibit specific courtship behaviors such as fighting and display to attract the females of the same species only. These signals are not identified by females of the other species. It represents behavioral isolation.

This is called a joint. A place where two bones meet or come together is called a joint. The two bones are separated by cartilage to keep them from rubbing together.
According to the Law of Conservation of Energy, energy is neither created nor destroyed. Technically, it is impossible for the plant to produce energy twice this input. It could only be possible if an external energy is required to create a reaction that would create more energy. This external energy could in the form of energy or another chemical containing potential energy.
