How Is the Following Paragraph Consistent with the Nature of Science

Multiple Choice

How is the following paragraph consistent with the nature of science?
This is an excerpt from the NASA NEO website. "As is often the case, the possibility of future Earth impacts for some near-Earth objects cannot be entirely ruled out until the uncertainties associated with their trajectories are reduced as a result of either future position observations, or in this case, heretofore unrecognized, pre-discovery observations. When these additional observations were used to update the orbit of 2004 MN4, the uncertainties associated with this object's future positions in space were reduced to such an extent that none of the object's possible trajectories can impact the Earth (or Moon) in 2029."

A) Science relies on empirical observations.
B) Science is tentative.
C) Science is limited by technology.
D) All of the choices are correct.
E) None of the choices are correct.
