Final answer:
The statement is true; heat released by condensation of water vapor inside a hurricane is the most important energy source, driving the storm's development and intensification through a positive feedback loop. The correct option is A.
Step-by-step explanation:
The statement that the most important energy source for a hurricane is heat released by condensation of water vapor inside the storm is true.
Heat energy is critical to the development and intensification of hurricanes. When water evaporates from warm ocean surfaces, it removes heat from the ocean. This water vapor then rises into the atmosphere, where it condenses into liquid droplets in clouds, releasing the stored heat, which in turn causes the air to rise and expand into colder regions of the atmosphere.
This leads to more condensation in a positive feedback loop, which dramatically reinforces and amplifies the storm's power. This process not only drives thunderheads but also is the primary mechanism behind the formation and strengthening of hurricanes.
Hence, Option A is correct.
