The relics of the Roman rule are still extant in England.

The correct answer is C. existent.

The word “extant” means “still existing or in use.” In this case, the relics of the Roman rule are still existing in England. These relics can be found

in the form of ruins, artifacts, and place names. For example, the Roman city of Londinium is now the city of London, and the Roman road Watling Street is still in use today.

The other options are incorrect. The word “hidden” does not make sense in this context. The relics of the Roman rule are not hidden; they are still visible in England. The word “scattered” does not make sense in this context

either. The relics of the Roman rule are not scattered; they are found in specific locations. The word “spread” does not make sense in this context either. The relics of the Roman rule are not spread out; they are found in specific locations.
