What conditions are required for a hurricane to form

- The storm must be developing over warm water. The water must be at least 80 degrees Fahrenheit. The warm water provides the energy for increased evaporation of water from the ocean surface. 

- The warm water must be at least 200 feet deep

- There should be very little wind shear in the area. Wind shear occurs when there is a difference in wind speed and direction over a short distance. Strong wind shear can stop the formation of hurricane eye walls. 

looks like the answer is     c     to me!
