The correct answer to the question is:

B. The Universe is not only expanding, but it is also accelerating.

Explanation:
1. Recent observations of the very high-redshift Universe, using Supernovae Type Ia as standard candles, have played a crucial role in cosmology.
2. These observations have revealed that the Universe is not only expanding, as previously thought, but it is also accelerating in its expansion.
3. This groundbreaking discovery, based on the measurement of distant supernovae, has led to the theory of dark energy, which is believed to be responsible for this accelerated expansion.
4. Dark matter, on the other hand, is a different component of the Universe and is not related to this specific discovery about the acceleration of the Universe's expansion.
5. Understanding the accelerating expansion of the Universe is a significant advancement in our knowledge of the cosmos and has opened up new avenues for research in cosmology.
