C is more realistic. You don't need 100000 features to make it work. Start with the core functionality because no one will have time to use those features. Otherwise, the burn rate will be very high before even starting marketing. I hope this helps; I'm saying these because I'm starting my app with community with some core features. I spent lots of time on development, it's now even more time on marketing. My 2 cents

Option C makes the most sense to me. Simply because 5 perfectly working features work best for me and my product.
