B)provide a backup system if one or more of the telescopes go down.

The main reason for using radio interferometry, which involves combining signals from multiple radio telescopes, is to achieve higher angular resolution in observations than would be possible with a single telescope. This is because the distance between the telescopes provides more information for resolving fine detail in the observed object or region.
