Answer the following questions:-(Software engineering questions on SDLC models):

i)How are risks associated with a project handled in the spiral model of software development?

ii)Which types of risks is better handled using the spiral model compared to the prototyping model?

iii)An example of a project where the spiral model can be meaningfully be deployed

iv)Consider that a software development project that is beset with many risks.But assume that it is not possible to anticipate all the risks in the project at the start of the project and some of the risks can only be identified much after the development is underway.As the project manager recommend the use of the prototyping or the spiral model?Explain
