SUMMARY
In a non-accelerating Universe, if the density equals the critical density, the Universe is definitively flat. This conclusion is based on the principles of cosmology, where the critical density serves as a threshold determining the geometric nature of the Universe. The discussion confirms that the correct answer to the posed question is option C: flat.
