In what instances might punctuated equilibrium occur? A) when the environment is unusually humid B) when the environment is rapidly changing C) when the environment is generally stable D) when the environment experiences gradual change overlong periods of time

B when the environment is changing rapidly

The correct answer is option B, when the environment is rapidly changing

Explanation:

Punctuated equilibrium is a form of evolution. In this evolution, the changes occur very rapidly in the environment as well as other living beings. After the phase of rapid evolution has completed, the organism enter into a phase dormant phase where things become static and the organism tries to equip itself with the rapid changes occurred during this phase.

Thus, option B is correct.
