Answer: B. Discontinuous development
Explanation: Discontinuous development is a type of development that occurs in stages, with each stage being different from the preceding one. When a caterpillar turns into a butterfly, it goes through a radical transformation in which it sheds its skin, its body shape changes, and it develops wings. This is a prime example of discontinuous development.
On the other hand, continuous development is a type of development that occurs gradually and smoothly over time, without any sudden changes or stages. This type of development is typically associated with growth, such as physical growth or learning new skills.
