I’m not sure. A) Waterfall seems too rigid for uncertain clients.

I practiced a similar question, and I think the Prototype model is definitely the way to go if the customer isn't sure about their needs.

I feel like the V-Model could work too, but it seems more suited for projects where requirements are clear from the start.

I'm not entirely sure, but I remember something about the Waterfall model being rigid, which doesn't seem right for uncertain requirements.

I think the Prototype model might be the best choice here since it allows for flexibility and adjustments based on customer feedback.
