Answer to Question 1

D

Answer to Question 2

The spiral model combines the waterfall model with prototyping and iteration. The spiral model starts as a small project that spawns other small projects as it moves forward through a spiral iteration. The result is a complicated approach that has nevertheless been very popular with government projects since its focus is on risk management. Depending on the risks identified, you can combine the spiral model with other approaches and methods. For example, if performance is important to the goal of the iteration, then you can plan for benchmarking, or if the flow of the user interface is of concern, then you can employ some kind of prototyping, simulation, or storyboarding.
