The correct answer is option option D

The enzyme-substrate model resembles the lock and key model. The key is specific to the lock and it cannot fit into some other lock.

timing of the cricket's chirps

Therefore, your answer is the third choice, or the timing of the cricket's chirps.

Hope this helped!
